Don't blame others for finding reasons from yourself.

There is an old saying that "nothing is difficult to a willing mind", which actually tells people that many troubles in life are caused by themselves and have little to do with others. It seems that some people always feel tired, but why are they so tired? It's not because I keep too many unimportant but extremely harmful things in my heart. So people will grumble and pretend to be dissatisfied with others or the objective environment.
