Always receptive to people's advice as long as I know it's genuine and I know that they are competent. Tbh if I see someone doing something better than me or someone with vastly more experience than me I don't really hesitate to get advise & feedback off of them - usually I straight up ask. Some of the most significant improves I've made have come from asking guys with more experience how they do x or y technique or even learning the tactics that they employ to get the better of me in a spar. One example I often use is doubling up on kicks if someone retreats backward in a straight line from you - seems obvious but isn't really apparent and you don't often see many people doubling up on kicks in that scenario - if at all. Unless of course you run into someone experienced who's learnt that & employed from many many years of training.
Whether I'm better than them or they're better than me doesn't really come into the equation. People have various strengths - someone might not be better than you but might be
able to pull of x technique better than you can & in a way you might not encounter with other people. They may also not be as technically good but tactically on point.
As for whether I take on that advice - it depends on whether it fits to what I already do tactically, strategically & with whatever weapons I like to employ.
If it doesn't fit or negates strengths I have or doesn't fit in well with what I do then I don't take it on board. But I always try to put the advice to the test in sparring before making a decision on whether I feel this is a useful addition or something that I might not be able to incorporate as effectively.
