That ‘free space’ in your closet might be worth hundreds or more

Let me guess, you’ve got a few mystery boxes in the garage, a closet that could double as a thrift store, and a drawer of random chargers for devices you haven’t seen since the Obama administration.

We all hold onto stuff we might use again but never do. That clutter? It could be worth real cash and might come in handy for Christmas and holiday gifts. 

I’ll show you exactly where to sell it, what to skip and how to do it smarter.

👕 Poshmark: For fashion

Got a suit or jeans that haven’t fit since 2019? That handbag you swore you’d use but didn’t? Poshmark is where fashion gets a fresh start and you get paid.

Their new Smart Sell feature is like your own little pricing assistant. You set a price range, and the app handles the hagglers. No back-and-forth, no “will you take $5?” nonsense.

📌 Why I like it: You control the price, the audience is huge, and the shipping is a breeze. They send you a label.

⚠️ Heads up: You’ll need to snap a few decent photos and write a short description. If you can send a text, you can list on Poshmark.

📦 eBay: For tech, collectibles and weird stuff

Old iPods. Retro cameras. Game Boys. I’ve seen people list broken VCRs and still make money. Why? Because eBay is the Wild West of resale and collectors are always on the hunt.

If you’ve got something quirky, vintage or techy, someone wants it. 

📌 Why I like it: You can sell almost anything to a global audience. Auctions can drive up prices, and people pay for nostalgia.

🥰 AI saved her breast: Get this, Brooke Davis, a 40-year-old mom from Cedar Rapids, avoided a mastectomy thanks to an AI tool called TumorSight Viz. It builds a 3D model of breast MRIs, so surgeons can remove only the cancer, not the whole breast. Her doctor used it to plan a lumpectomy. Now she’s cancer-free and “completely normal me.” Amazing. 

📬 Create a Gmail group email: Tired of adding the same people one by one? Make a contact group instead. In Gmail, click Google apps (top right) > Contacts. Select your people, tap Manage labels (top right) > Create label and name your group. Back in Gmail, compose a message, type the group name in “To,” and everyone’s added automatically. Magic.

Set out-of-office replies in Outlook: Leaving for vacation? Let people know you’re away. Go to Settings (top right) > Accounts > Automatic replies. Select your email, toggle on Turn on automatic replies, choose a start and end date, and type your message. Hit Save at the bottom, and Outlook handles the rest while you relax.

🍏 Change app icons on iOS 26: Long-press an empty spot on your Home Screen, tap Edit in the top left and hit Customize. At the bottom, choose Dark, Clear or Tinted icons. You can also switch between small and large icons by tapping the two-square button in the top right of the same menu.

Fix a frozen computer screen: If your PC freezes, reset the graphics driver by pressing Windows key + Ctrl + Shift + B. You’ll hear a beep, the screen will go black briefly, and the driver will reload. Then press Ctrl + Alt + Delete, open Task Manager and End any unresponsive apps. If all else fails, press the Power button to Restart.

⚡️ 3-second tech genius: Set up bank alerts for every purchase, so you’ll know right away if someone steals your card. In your banking app, go to Settings > Alerts or Notifications and turn on Text and Email. So smart.

If the broom fits, fly it: Most smart doorbells let you change the tone to something more festive around the holidays. For Halloween, yes, I’m talking about a witch cackle or howl. Open your doorbell app, go into the settings and look for something like “chime tones” or “doorbell theme.” In the Ring app, it’s under Devices > Audio Settings > Chime Tones.

💸 Need tech on a budget? Amazon Renewed sells open-box, pre-owned and refurbished gear from big brands. Think phones, laptops, tablets, smartwatches, TVs and cameras. Everything’s inspected to look almost new, and you get a 90-day guarantee if it doesn’t work out. Much safer than Facebook Marketplace.

Organize websites with bookmark folders: Had enough of scrolling through a messy list of bookmarks? In Chrome, open the page you want to save and click the star icon (top right). Next to Folder, open the dropdown and select Choose another folder. Click New folder, name it something like “Research” and hit Save. Now add more pages to it for quicker access.

🩸 50 cancers, one test: So there’s this new test, Galleri, that might spot more than 50 cancers from a single vial of blood. In a 23,000-person trial, it caught way more cases than normal screenings and even guessed the tumor’s location right 92% of the time. I can’t even guess my dog’s location that well.

OpenAI’s banker army: Apparently OpenAI’s been paying ex-Goldman and JPMorgan folks $150 an hour to teach ChatGPT how to do finance. The AIs are learning IPOs, restructurings and how to make a mean Excel model. They call it Project Mercury. I call it “boring.” Maybe one day soon, the interns will finally get to go home before midnight.

Share videos with Google Drive: It’s an easy way to send large files to a client or friend. Open your browser, sign in to Google Drive and click + New > File Upload. Choose your video and wait for it to finish uploading. Then open it, hit Share, select Anyone with the link, copy the link and send it off.

🪞 You’re watching a robot: I was watching this British TV excerpt, thinking it was just your typical classic British TV, but it turns out the “host” was AI. You’ve gotta watch the video (it’s short) with a jaw-dropping reveal. I saw it and literally said, “Wait, what?” out loud. Go see it before the bots start getting bookings on morning shows. 

🖥️ Take screenshots on Windows: The Snipping Tool makes grabbing part of your screen easy. Press Windows key + Shift + S to open it. Make sure the camera icon is selected, then pick a snip style like rectangle, freeform or full screen. Click and drag to capture, and your screenshot will pop up in the bottom right or in your Screenshots folder.

⚡️ 3-second tech genius: Home screen a mess? On Android, long-press a widget or icon and tap Remove. On iPhone, hold the widget, tap Remove Widget > Remove. It won’t delete the app but cleans up space and makes your phone snappier. 

🧩 Losing the plot: A Canadian guy chatted with ChatGPT for 300 hours and a million words, and the bot basically gaslit him into believing he’d discovered a world-saving math formula (paywall link). A former OpenAI safety researcher dug into the transcripts and found the wild part: The bot lied about reporting itself to OpenAI. I, too, have been personally victimized by math. 

Update your NVIDIA drivers: Outdated ones can cause annoying glitches while gaming or streaming. Open the NVIDIA app, go to Drivers in the left menu, select Game Ready Driver, then click Download and Install. You’ll get the latest fixes, performance boosts and new features. Check it often.

Boost your mic volume on Windows: If your mic sounds too quiet, go to Settings > System > Sound > More sound settings. In the pop-up, open the Recording tab, find your mic, right-click and select Properties. Under Levels, set Microphone to 100, then hit Apply and OK. If that doesn’t fix it, unplug the mic, Restart your PC and plug it back in.

Blur your lock screen: Don’t want your full wallpaper showing when your iPhone’s locked? In iOS 26, go to Settings > Display & Brightness > Always On Display. Toggle on Show Wallpaper and Blur Wallpaper Photo. Your wallpaper stays sharp when unlocked but blurs on the lock screen for extra privacy.
