I have been treated like this before, because the other party's performance is too obvious, and I feel it. The feeling at that time was that she shouldn't be jealous of me because I have been working much harder than her. Maybe in her opinion, I was purely lucky and got everything easily, but the fact is not what she thought. If I can completely do what I do, many people can get where I am today, but others are not willing to work so hard. These people have no right to be jealous.
Do what you should do in a down-to-earth manner, and you will have a fruitful day. Comparison is the only way to compare, which is the embodiment of self-motivation. Just grasp the center of gravity. How powerful you are depends on how much you have done over the years. Only looking at the results and ignoring the process will make people psychologically unbalanced.
In addition, don't be discouraged when you see others better than yourself. This man happens to be with you. If she was born in the next city, you may never know her, but there are still people in this world who are better than you in some ways. When you see her, you have a chance to know what she is good at. This is a kind of resource.
In a few years, you two won't be in the same place. At that time, I hope you can make progress under the competitive spirit, instead of being discouraged year after year. One should learn to admit defeat. You can't always stay ahead of the people around you. You need stronger people to appear in front of you occasionally, so that you can have a chance to know that people can do better.
