Don't expect anyone else to support you. Maybe you have a trust fund. Maybe you'll have a wealthy spouse. But you never know when either one might run out. Be careful whose advice you buy, but be patient with those who supply it.
Advice is a form of nostalgia.
Dispensing it is a way of fishing the past from the disposal, wiping it off, painting over the ugly parts and recycling it for more than it's worth. Whatever you mind can conceive and believe, it will achieve. Dream great dreams and make them come true. Do it now. You are unique.
