About never say "no"
In my mind,I should do anything in my heart,and never give up.Maybe that is a very good manner in most peoper's opinions.But now,I changed,and I find that's not the best way to do anything.
In our life ,we always may meet failure and success.Not every failure you should continue doing.If you want to be a accoutent ,and you try your best to make it come true,but after two or more times failure ,you must consider it once a more and carefully.Whether it is right ,and is there any other job more suitable for you.So you must learn to how to give up and how to choose.The reality is more important at days.
Never say "no" has not always a good habit .Of course ,I don't refuse it ,I think we should stand on some times and also should give up some times .Maybe it bring a lot of treature to our life.
