Well, I am a couple years past 25, but since I was thinking about this earlier today, I hope you don't mind if this 27-year old participates...
First of all, my most important life goal is to get married and have a family.
Other goals, in no particular order:
-Own a house (normal house--nice, but nothin' fancy)
-Get a masters degree (admitted already)
-Finish my multi-engine and multi-engine instructor ratings
-Get my CFI-Glider
-Get my ATP
-Get at least one jet type-rating
-Stay in good physical shape; exercise regularly
-Design, build, and fly my own RC
-See a NASCAR race live
