After a period of fitness, you will feel extremely confident when lifting iron in the gym. .
But once back in real life, people who feel inferior will still feel inferior in the face of the pressure in life, and they will still be very fragile when they are fragile, which is not essentially different from others.
Fitness will not make your mental endurance stronger, nor will it make your mental strength stronger.
Having said that, intelligent fitness will make you a little more self-disciplined than the average person, and you will start to pay attention to diet and rest. You can also understand that your quality of life will improve and you will feel that you are in control of your own life.
As for whether fitness will make people cheerful and optimistic, I think it has nothing to do with it.
Some people are born with a good attitude and are cheerful and optimistic about everything. There are also people who are born with poor mentality, and later they have experience and are optimistic.
Personally, the most important thing is to learn to accept yourself with inferiority and admit that you are inferior to others. Admitting that you are inferior to others and accepting what you can't bear doesn't mean that you are doomed to be inferior. It is to let you know yourself better and know where you need to change and work hard.
Inferiority can be a stumbling block to crush a person, or it can be the basis to inspire fighting spirit. Although some people are full of energy at ordinary times, they all have an inferiority complex. Therefore, don't think that inferiority is your own problem.
