Why even consider it?
I never saw myself as an aggressive person, and the idea of punching people did not appeal to me. I am not great at sports either, but yet I took up boxing. Becoming better at the sport, despite not being great at sport, makes the achievement more meaningful.
Boxing is intense, but I like the hard work, and some mild suffering. At the club where I train, there is not much room for chatter or distractions during sessions. This keeps me busy which is great. Boxing is not as dangerous as it may seem when you are in the right club. It is worth a try. You do not have to go competitive.
Appearence matters, and physical activities can improve it. However, I wouldn't recommend overdoing it. Without suffering and inequality, life would be boring. Effort brings reward.
Man, the bravest animal and the one most inured to suffering, does not repudiate suffering in itself: he wills it, he even seeks it out, provided that he is shown a meaning for it, a purpose of suffering.
– Friedrich Nietzsche, On the Genealogy of Morals, Third Essay #28
Why I considered it
It was a combination of factors. Nietzsche's ideas on why the body is so important and an inspiring video of Michelle Khare, which showed that boxers have a lot of discipline. It is a bonus that the club I train at is close to home. It is perhaps one of the best things I have ever considered.
