Don't doubt many things first, others treat others with sincerity first, so that they will have no regrets.

Of course, everyone should carefully analyze many problems and be sincere in everything. If we find that others don't take ourselves seriously, or don't want to continue to communicate with ourselves, then we can stop here.

But if you start making friends, you are not sincere. You will live very tired, life is too short, there is no need to live so tired, you must pay more first, and you will certainly gain something.
