We often say, "sincerity is nirvana", indeed, in our interpersonal communication, those who are sincere, we will treat each other sincerely, and we also hope that others can treat us sincerely. Sincerity is a good quality, if there is no sincerity, then the relationship will become a game of you guess me and I guess you, there can be no deep relationship, without sincerity, then we will only attract those refined egoists. So let's not be afraid to give sincerity, we give sincerity first, before we can filter out those who are not sincere to us. 
I remember once having a friend of mine who was like this, and she always used to tell others about her experience first. I still remember when I first met her, I asked her a question, and she could say ten words, whether it was good or bad, and she said it all in one go. Later, another friend of hers, who is also a friend of mine, commented on her to me, saying that although she is a very sincere person, she always feels that she is complaining, has too many negative emotions, and does not like to associate with her.
It's the same in love, if someone you don't like reports your whereabouts and shares daily chores with you every day, will you fall in love with him? The answer must be no. Do you remember? When you were in college, you fell in love, at that time, you were extremely simple and beautiful, you talked about dreams, life, and the future, but as soon as you graduated, you faced your respective career choices, even if you had been together for a few years, and then you loved each other, you still chose to break up. When you don't have the strength to give the other party a good life, your sincerity can't move the other party, and you won't be moved by giving up everything to be with you because of an unmotivated person, you will only feel that he is annoying, want to get rid of him, and even feel that his sincerity is a burden.
Sincerity is a kind of ability to others, in the new year, may we have more of our own abilities in addition to sincerity, such as the ability to make money, the ability to learn, the ability to manage ourselves, the ability to love ourselves, and the ability to manage strong emotions. These abilities are the self, and may we all cultivate into a strong self. When we truly have ourselves, we can talk and laugh, not suffer from gains and losses, and not try to move others with sincerity. At that time, we were a flower that attracted butterflies.
