This is the truth. When you face people that know what they are doing, then your perspective of other people change. You see that small skinny guy not as a wimpy looking guy but that guy in class who is flexible as hell and has some good speed and timing. You see that middle aged guy who looks in decent shape, walking around with his family, not as some middle aged dude with a family but that older purple belt who just wrecks you with his old man strength and skill to match.
It's called the Dunning Kruger effect. Experts usually underestimate their skills while non experts oversestimate their skills. It happens with fighting all the time. New dudes come into class thinking they are going to do this and that, then reality sinks in.
lol...literally describes my pov, and i was already cautious or respectful of what people could do before training; training just gives me a rational line of thought based on prior experience that brings me to that conclusion.
after sparring (striking grappling or mma) w/some goofy looking college guy, or some kinda out of shape dad type and really getting pushed you no longer make assumptions demeaning what someone could do to you; cus your experience has show you the exact opposite.
i actually had someone tell me i am super cautious around really polite or non confrontational guys; cus i sparred you fairly regularly and you were putting it on me (in spots), so now i'm thinking they are calm and polite for a reason...not just cus they are push overs.
