That said, I can see his point. Anyone who responds to a criticism of having no motivation/ambition/independence with "hey, fine, whatever" and describes her activities as "going to school, writing a b-plan, etc", seems a bit too nonchalant about life.
You seem to lack passion. Is there anything in life that gets you fired up?
Second thoughts can generally be amended with judicious action; injudicious actions can seldom be recovered with second thoughts.
