1. That I'll make the wrong decision.
  2. That this wrong decision will somehow affect my life in ways that I won't be able to fix.
  3. That I won't be able to make the decision at all because I'm too paralyzed. And the opportunity will pass me by. And I'll never get another chance. Ever.
  4. That people will laugh at the decision I've made. Or mock me or some other similar sentiment.
  5. That I'll make the 'right' decision and it will not turn out how I had hoped, thus making it the 'wrong' decision.
  6. Whether I am too old to make a big decision that could potentially alter the course of my life.
  7. Whether there is some kind of service or company I can hire that will make the decision for me.
