《How to win friends and influence peoplel》

when I have read the chapter one of the book
《How to win friends and influence peoplel》，I think I knew very significant truth that everyone should never complain others and just find problem from yourself.
In our life，we may meet many troubles because of others' errors.But if we involved in these troubles，we shouldn't blame other，because it would not help us solve the problem.On the contrary，it maybe make the
circumstance become worse and worse.
