How could I keep stupid for so long?

I get amazed at how could I survive with useless thinking for so long.
How could I bear that stupidity for so long ?
I really could not understand now when I look back. How could I maintain it for so long the irrational and totally stupid kind of thinking.
I feel lucky and full of energy now .
He he, never let useless thinking come into my life make me tired again. I enjoy my life now. Really love it .
