Make a blanket for a someone you love using clothes you no longer wear, an iron, and Stitch Witchery. No sewing skills needed. Spray it with your favorite scent and they'll have a keepsake to remind them of you for years to come.
Handwrite a letter (on real stationary) to a person who inspires you. Tell them why. Can't think of anyone? Check out togetherrising.com for a list of people needing a little encouragement.
Find a tube of lipstick. Write a note on the bathroom mirror to let the others in the house know how much they mean to you. Not that sentimental or just can't think of something to say? How about writing a joke or even a Tic-Tac-Toe board to play with someone throughout the week.
Have an issue that's bothering you? Pick up your phone and call your Senator. No use complaining about it if you don't actually ask for change.
Bust out the cookie sheet, cake pans, and creativity to whip something delightful. Eat, share, repeat.
Turn off the cell phone. Put the laptop away. Unplug the wifi router. Use the time to snuggle on the couch, play a game, read a magazine (hint, hint) or just enjoy good conversation with family and friends. If you like this time spent offline, consider putting your wifi router on a timer so every day you have a reason to gather without any devices.
The best way to feel good about your life is to express gratitude for what you have. Take some time to write down every little thing you can think of that you're grateful for. Big or small, it all matters, so leave nothing out. Revisit your list from time to time (or every day) when you're feeling salty.
Turn your home into an obstacle course. Create "events" and start your own Winter Olympics. This is fun for kids and also totally acceptable for an adults only party with celebratory cocktails on the podium. It's fun, healthy, and gets you off the couch and away from the screens. You may even have so much fun you start a annual event.
If you must go online, at least do a little good. Start a thread in a public Facebook group listing things you have that are fee to someone who needs them. Ask your friends to do the same and show the world that the kindness of strangers still exists.
Write out a birthday card for everyone in your family, your friends, coworkers, and neighbors. Address and stamp them so they are ready to go in the mail three-four days before each person's birthday.
