Hmm, you could start by making a list of some of the things that you have accomplished. You could also make a list of things that you would like to accomplish, and come up with steps for getting there.

If you're having a hard time coming up with ideas, try using some of the assessments here: http://www.authentichappiness.sas.upenn.edu/ The Values in Action Strengths Questionnaire might be a good place to start.
