Earlier this year I wrote about an economist who lost 14 pounds after giving himself a rather stringent financial incentive (he agreed to pay a friend $500 if he didn’t lose the weight).
Website 43 Things gives people a less draconian source of motivation for accomplishing their goals: some public encouragement. Simply sign up, list your goals, and connect with other people who have similar aspirations. You can track your progress as it happens, and cheer (and be cheered by) others.
There’s also a very cool feature that enables you to browse the most popular goals (lose weight, write a book), the newest goals (make ceramic, play “Twinkle, Twinkle, Light Star” on piano, as of this morning), and the most popular achieved goals (fall in love, get a tattoo).
