thinking about my feature

sometimes i feel stupid when i'm thinking about my feature; where i will study (i mean university) ; what my job ; will i be rich or poor, because it just make me stress.
many people says : " you just need enjoyed your life, because life just once" "about your feature just lei it flow"

but.. some people says :"you need thinking about your feature girl, if you want to be success women"
yeah, i think that opinion is true. if i make shift now, i will happy in feature.
