Managing your life...
Say "yes" often; you will open new doors, meet new people, have new adventures.
Learn to say "no" with conviction and finality. This will close doors, keep you from meeting extraneous people, and save you from mis-adventures.
Dance often!
Remember, you do not have to dance to every tune. Especially tunes you did not request!
Be kind, and sensitive, and empathetic to other people.
Be willing to disappoint others; be swift, cold, and sure.
Remember: you want everyone to be happy/you can't make everyone happy! It's not your job!
