how do you tame the lion

howdy I am new here so bear with me. Naturally agressive lots of poker comes somewhat easy for me ,if any of it can be called easy. I can play weak or medium or good drwaing hands well. Strong hands that are losers are something I find nearly impossible to get away from. Having no fear is a good thing , but when it stems from apparent stupidity not so good lol. I have to admit this occurs whenever I think I have the best hand regardless of any persuasion to the contrary I.e big bets the other way.
