Some Advise

An advise was thrown my way by a buddy just recently.

As if in random, he keeps repeating them.

One time he says, " Good timber does not grow with ease. The stronger the wind, the stronger the trees."

At another instance, he will snap, " Honest criticism is hard to take. Particularly from a relative, a friend and acquaintance or a stranger."

But this one, I can't understand, " The fact that nobody understood you does not make you an artist."

Kindly, please enlighten me.
