Is anyone else indecisive on what career to pursue after high school?

That's totally normal. Ideally, try and find something you're interested in, and put time and effort into get very good at it.

It'd be even better if that thing is a trade or skill that is very in demand. Currently, I'd recommend getting into coding or design. It's creative, it can be a lot of fun, and it's a booming industry at the moment.
