Believe that people can change, if you want to change others, you need to try to change yourself first. Don't always think that it's easy to change, but you can't change your nature. Sometimes, with faith, people can change. Maybe it is for friendship, maybe it is for love, or maybe it is for family. It is important to look at others with a developmental perspective. Especially for people who love each other. Maybe you can not tolerate some of the other person's faults, if you if you love each other, give him the opportunity to change. However, strict requirements for each other at the same time, but also strict requirements for themselves, for some of their own intolerable for each other's faults, the same to be corrected. Never be strict in treating others, lenient in treating yourself. Doing so will make the other person sad and disappointed.
Be sure that any pain or adversity has a meaning, and try to find out what it is. The pain you are suffering now is not meaningless. Life is not what it seems. People will run into a lot of pain in their lives, which we can't avoid. Suffering can make one depressed or inspire one to fight. Pain hones one's will, so that people will not be easily defeated by difficulties.
The beauty of a part is also beauty without asking for the whole. The pursuit of a perfect life is everyone's dream. But does this perfection really exist? Is it worthwhile to spend our whole life just to pursue that perfect moment? Everyone has shortcomings, everything will have shortcomings. Look at people and things, first see its good side, if you think this person is worth your time, I to you must be able to tolerate each other's shortcomings. Don't keep your eyes on the ugly side, you'll never find happiness that way, you'll never be in a good mood.
If it is because of a certain thing that makes you unhappy, then you go to bravely put this thing to try to do, even if it is a failure, you know the result, just like to your crush on the girl confession, even if the person refused, you will not feel sorry.
