People say "you are too your, there is a long way ahead of you", even tough I'm 20.

Oh absolutely Leaf
I gather you're a thoughtful fellow while most of us are merely victims of Cause & Effect 'til we begin to develop some insight about age 42. The trick is to continually ask yourself, am I doing the right thing

I emphasized this with my two boys and was apparently successful

….with just a few reservations now and again

I should say 52, when began looking back on my mistakes

Never mind anything else, first do the right thing, then second bring up kids who know it too
