I'm betting you started far earlier than 6th grade. Somehow, as with me, I see you sitting in the woods, hammering nails to make them straight and then pounding a million of them through scraps of wood into a tree trunk to make the ladder for your soon-to-be treehouse!
... and, I'd be willing to bet you had one of those little work benches where you could take the wooden hammer and smash a block through a square hole - or tinker toys that tightened up real fast when you gave them a whack.
'Fess up - you started at 4 years old!
