What should I do if I want to be invincible?

Give you four words, that's to foster strengths and avoid weaknesses. First of all, analyze your own advantages, and then through continuous learning, training and strengthening, make your advantages more and more obvious and stronger, so that you can stand out from the crowd in at least one aspect. On the other hand, find your own shortcomings and consciously correct or improve them. If it really doesn't work, try to avoid it so that others can't take advantage of your shortcomings. Do these two things, and you will become invincible.
