Don't think that when you do something, there will be results. If you don't have results, it means you haven't worked hard enough, it means you are not good enough. It's not that the method is wrong, it's that you don't believe enough. Believe first, then you will go all out, go all out and persevere. Only then will you have a chance to see the results.
You should not keep blaming others, you should always review yourself.
Complaining about others is also hurting yourself.
Blue sky, white clouds, green mountains and green water, I hope to live in such an environment forever
