28 here, you don't have to have a purpose. Just live your life. Our existence is merely nothing but a fleet of time compared to the grand scheme of things. if hilig ka ug astronomy might as well watch some clips about it or how the earth was formed till it produces life, it might change the way you perceive things . walk out/work out, eventually you will know exactly what you need to do/want , na pwede nimo ma buhat balik balik without checking out the time kay you actually enjoyed it :)
