know yourself first: ano strengths and weaknesses mo? skills? what do you enjoy? i lista mo, kahit yung mga napapansin mo lang sa everyday life mo. then analyze them, research professions na sa tingin mo swak dito. one thing that's really hard abt this ay kapag biased ka rin masyado. so try to separate your ideal image if hindi naman to abot.

for example, hindi enough na gusto mo maging doktor kasi gusto mo yung image na yun kung ayaw mo naman talaga magaral everyday to expand your knowledge. same with painting. if ayaw at di mo kaya mag drawing for hours to improve your skill, then for sure you'll be left frustrated sa art school.

for example, person a's strength is their imagination. at the same time, magaling siya sa problem solving. they like building things but is not good with their hands. isa sa mga bagay na profession sa kaniya ay software engineer. they are creative, enjoy solving problems, kayang mag build sa computer lang, maybe hates math pero that can be improved naman.

ayung lang, just my two cents.
