Finally, I found the correct rhythm of working.
I was always thinking that I may work in a wrong, low efficient way. I was afraid of making mistake. As a result, I was hesitating and wandering without making any progress.
Yesterday I saw a sentence from a MSN friend's signature.
" A man who asks is a fool for five minutes, and a man who never asks is a fool for his life. "
So the secret is to think, to do, to think, to do...
Do not hesitate. Do not be afraid of losing face.
A thousand miles is made up with steps.
No one can be perfect from beginning.
Rush!
