The biggest thing I've learnt from boxing is discipline. If you lack discipline as a boxer, you will get outboxed and knocked out very quickly. Boxing is one of the most difficult combat sports you can ever take up.

I completely agree. Self-discipline is essential, or you'll be defeated by your opponent. You need to be disciplined in attending your training sessions, maintaining a healthy diet, and so on.
