I agree with you about people who say just do it!. I have a counsellor telling me that with my avoidant personality disorder. It is easier said than done. I agree though that if I take teh first step toward doing something with little consequences it is fine. However some decisions in life have very big consequences if we just hop into it or "Just do it".

I took that advice once and moved to a new province and ended up in a place I could not find good work. I had sold a home bought and paid for. Now I am back to renting crappy apartments. so "Just do it" is not always the best answer.
