How can I choose an carrer with so many options?...

Hello! Hope you're doing fine right now, if not, the best and only the best for you, friend.

There are a lot of idleness going on in my life, I don't have an something to follow (like a family member with an carrer that can inspire me), nor an wish for my future... I kinda need to choose shortly, because there's going to be a competition for a course integrated into high-school, I don't want to get there and don't know what to study for, or what I'll be doing really is what I wish for... I need an north!

Still in 9th grade by the way, can't help but be a little premature. Also I don't speak english naturally...
