when to start?

simple question need's a simple answer. NOW. approximately, human is in his/her "best" at the age of 17-30, this only gives a 13 year window of oppornity, and it goes fast,  way too fast.
to gain succes afther/before this is not impossible, not even as hard as may seem, but its deffinetly isn't as its best.

13 years gives 13x356d = total of little more than  4500 days... quite much...well, it isnt. to live in future isn't that good.
