I don’t know what to do with my life(i’m 16)

how can i follow my passion when i don’t exactly know what my passion is? And why do we only get one life passion what if i want to do many things? and what if these many things add up to most of my life in college? what if i don’t choose to go to college and i choose to live a simpler life and travel? how do i travel with no money? and how do i constantly travel when i’m constantly busy with my career but yet it pays for me to travel? and what if i regret the life i choose?
