As the "world's largest goal-setting community" you may already use 43Things to maintain your personal 'bucket list', but if haven't done so yet, you should check it out. It really is a positive place! 43Things is a different kind of social network where members list their goals, share their progress, connect with others with the same aspirations and cheer each other on. Members are limited to a list of only 43 goals which encourages you to discover what's most important to you and focus on completing each item on your list. You might also want to try 43Places -- a community for travel enthusiasts.
