In adolescence, it's 'How do I fit in?' In your 20s, 'What do I want to do?' Your 30s, 'Is this what I'm meant to do?' I think the trick is living the questions. Not worrying so much about what's ahead but rather sitting in the gray area; being okay with where you are. If you can find the parity between 'Where am I going?' and 'What's my purpose?' you've got two pretty solid pillars for your coffee table.
