Wireme,
from my experience, just let him grow up.
I would always suggest lots of trees for climbing, fishing, bush zones to explore and an early introduction into READING.
My own grew up with Enid Blyton.
Sit and read to him.
Bonsai is an intellectual pursuit, and attracts two types, the superficial who wants to show off and those who really think.
Thinkers read.
Thinkers often create.
Thinkers often invent.
All of my sons are in Science Research over in Europe.
They have always read.
Classical Literature, Science magazines and stuff
Good Luck with the potential.
Good Day
