I've graduated from highschool and I cant seem to know what I want to be/ what do I want to do in the future. The future's blurry to me. I like & enjoy most of the courses the colleges are offerring. Be it math, science, accounts, engineer, meds, film director, anime producer, computer expert.
AHHH !!!
All I want is to be rich & happy.

Do I follow what my interests are? or
Do I follow what are the jobscopes with the most amount of salary? >_<

I'm still in high school so idk if you ant to take my advice into consideration but if I was in your place I'd see whether my interests would get me enough money and if not, move on to the next until you find one that could get you a good pay.

OR

You could do what I will probably do (keeping in mind that there isn't college in my country) and choose me top interest (music), but then choose a different course like Microbiology or some shit that will get a good paying job and focus on that because most of the time your interest will be something you find easy.

I hope this helped and I'm sorry for my bad english (it's my first language but dear lord it's my worst subject haha)

Hmm... What if you choose to be undecided for now about your major and take half of your course selections from the ones you are really interested in and half from the ones that can get you high-paying jobs? You can experience what both routes can offer and decide later on what area you want to major in.
