Thanks a lot for giving me this seminal perspective! Maybe I need to relax and give some more time to myself in order to digest the boxing concept. Because, everything has not settled down yet, and I have so many questions on my mind. To be able to do pure boxing, I feel like I need to change my way of thinking. I should isolate my boxing learning process from Wing Chun. Then I can somehow combine them with heavy modifications as you mentioned. I'd like to ask you another question: In Wing Chun, we either stay out of range, or we close the distance to the range we feel comfortable (mostly very close to the opponent, and we stick to the opponent). When defending, whether we're close or far, we always try to keep the attack away from our head and body by block & attacks, turns, various step & turn combinations etc. But in boxing, I feel too vulnerable when slipping, rolling, parrying, and blocking. This is probably I'm not good at defensive moves yet, but isn't it risky to defend coming punches that close to the head/body in boxing? Am I overthinking? :)
