It's not that boxing is good, it's that people who practice boxing are good. No matter what kind of martial arts, it is very powerful to practice to the depths of the essence.
Premise:
Self-study 10 years, it is better to be a "master": both Tai Ji Chuan and Taekwondo have fake masters. Wrong root, master. It's no use practicing hard.
Boxing is self-evident: with a good master, it is useless to insist on it yourself.
Fist to the flesh: practicing martial arts is to hit people. Dare not, don't want to hit people, don't practice martial arts.
If you want to hit someone, learn to be hit first: if you are afraid of getting hurt, don't practice martial arts.
From the perspective of fitness:
Do not practice martial arts! There are many ways to keep fit, and through practicing martial arts, there is a great chance of joint injury. It's a good choice to get a card at the gym if you have the money, but don't go running, climbing mountains or swimming, just like dancing in the square dance.
In addition, if you meet an Qi practitioner, directly challenge him to do Sanshou. If I can beat you, learn from him. I don't know how to hit people. I only know that the exercises of "keeping in good health" and "nourishing the heart" are Tai Chi exercises, not Tai Ji Chuan.
