Career path

I honestly dont have a clue what i wanna be when i graduate high school soon. Ive thought about this mulitple times and ive talked to my councillor and taken career tests online (too many to count) and i always think about the career i wanna do at the time but i always tend to think about the negatives about it. I.e: i currently am thinking about taking up law school and becoming a lawyer and as it makes great money the negatives are that i need a bachelor's degree before i apply do law school and what if i dont get in? Also ive read that your salary can fluctuate depending on thw amount of clients you have that year and i don't want to be worrying about making money with my career :/ Any lawyers on here got any advice ?
