30 days of yoga:
Resolve to do yoga at least once a day for a month. Doesn't matter how long the session or how difficult.
30 poems in 30 days:
Pick up and write a poem each day, doesn't matter how long it is or how "good."
30 days of donation:
Each day select an item that you own--be it canned good, article of clothing, book, or monetary amount--that you will collect and donate to someone less fortunate or to an organization like Good Will, ASPCA, The Homeless Voice, Better World Books, your local library, a panhandler at the light, Red Cross, or any other person/organization that would do better by having it.
30 days of 30 contacts with people that you know:
Everybody knows at least 30 people, some better than others. Moreover, everybody knows at least 30 people who they don't speak to regularly and might appreicate a call, an email, or a letter to let them know that you're thinking about them. Each day, contact one of these people. It could lead to a conversation or a drink or less or more.
30 days of new musical artists:
Log onto your Lastfm or Itunes and listen to the catalogue (or what you can find) of a musical artist, group, or band that you've never heard and take a listen. Find one each day of the month and listen to a bit of them at work or at home. See if you like it. If you do, what's stopping you from getting an album or going to a show?
30 days of walking up and down the streets of your neighborhood:
Living in driving commute cities takes its toll on you. For this 30-day challenge, take a walk up and down your street and/or adjacent neighbor streets either for exercise or for fun or to just plain decompress from being indoors all day long. If it's raining, use an umbrella.
30 days of 30 new vocabulary words:
Merriam-Webster's online Word of the Day notifications have fallen by the wayside because, well, it's redundant to see them every day and delete them without even opening them. But what if you randomly selected a word from the dictionary each day and committed to reading the definition and applying it to some aspect of your day, your life, or (better yet) your conversation that day?
30 days of 30 puzzles: Daily crosswords don't have to be completed to be enjoyed. Neither do Sudoku games. The newspaper prints one each day and plenty of online versions are availabe that can aide in completing this resolution. Pick one type of puzzle/game (that you don't already do daily) and play it all month long.
30 days of journaling:
Not everyone keeps a journal because, well, other things come up. So, for 30 days, take some time to write a journal entry each day. It can be a dream journal, a classic "Dear Diary" entry, a travelogue, a food/exercise journal...or any other kind of personal entry that you can think to make.
30 days of jumprope:
I can think of worse things than taking five minutes out of my day to jump rope. If you track your number of jumps in a minute each time, you can challenge yourself to beat your previous record.
30 countries in 30 days:
Look up a country on Wikipedia or online at their national homepage. Each day, pick a different country. Try to be eclectic in your choices and look for places that you know little or nothing about. It's amazing what's out there when you start looking. You can learn about its national holidays and celebrations, its history, or its climate. Hell, you might even just learn that it exists. If you're really into it, you can chart your progress and journal your virtual travels...in your 30 day journaling challenge.
Even if it's the middle of the month, it's no reason to put it off. You can count to 30 starting today. And I've got a place that I can record my progression...since I'm journaling. For the record, I'm starting with handwritten daily journaling for 30 days AND walking my dog up and down the neighborhood streets at least once a day for 30 days.
