Simple, you Practice. Or if you dont like that then you could: learn, study, rehearse, become seasoned, build up, discipline, do again, drill, exercise, go over, habituate, hone, iterate, polish, prepare, recite, run through, shake-down, sharpen, train, try out, tune up, walk through, warm up, work, work out, or any other Synonyms i haven't mentioned.
Sorry for the smart ass-ness... but there isnt any magic "insta-good" secret out there (minus cheating of course). The people who beat you have just logged more hours than you.
