1. spend more money it than i should and can afford.
my second mistake is having been thinking perfect and ideal = better, in which case i always have the mindset for triving for this better ideal sound. i've bought headphone and speakers that have this ideal qualities, and they are acclaimed products. usually these qualities are; being more neutral, more flat, more details, more accurate, better depth.
only after a while i realize i hate the sound. cant relax and enjoy it. every human ears frequency curves are different from each other, and even the left ear hear different from the right, and how much you enjoy a specific sound will also depend on your personal characteristics. you're a soft and laid back person, an agressive speakers doesnt suit you. more expensive is not equal to better sounding.
another thing is i dont have to put up with uncomfort to enjoy good sound, aka i dont have to put up with grado fatigue to enjoy its bass, or uncomfortable heavy headphone that strain my neck. comfort is the essential for audio listening. because audio listening, in away is something people call antisocial, (although the correct definition of antisocial mean something else in psychology) a hobby you do to relax and get off the daily stress. i'm not going to make this hobby to cause me more stress, i came to it in the first place to help me get off stress.
the thing i have done right: buy gears that produce sound that is pleasing to me, instead of 'better', pride (feeling of superiority over the others), or good look. also some luck with spending money on underdogs products and being satisfied with them. my way isnt that practical to follow though.
i am an advocate of this sound signature idea, where matching equipments receives different sound. therefor from now on, my audio goal will be syngergy and balance. the idea of wholeness.
being obsess in the sound instead of loving the music is a bad thing.
