How important is it for you to know what you wanna do with your live before you finish high school? Very... Unfortunately it just isn´t the case in every single situation. One has to experiment a little in order to discover what they are good at. So many crappy private schools are there right now. Especially where I come from, that mislead students so badly. High-schoolers are driven into making the wrong decisions cause they´re bombarded with ads from the aforesaid schools. I for instance, was literally forced by my folks to study something I didn´t wanna pursue. As a consequence, I got really frustrated. Nonetheless, I found my way soon enough. What I mean is that I actually ended up drifting into what I liked. Most people find themselves in the same situation I was. In fact, previous experience also does help. Though, it´s much better not doing something that is gonna make you waste time and money. Sadly, local governments perpetuate injustice by allowing private colleges to keep profiting with people´s ignorance. They allow this to happen cause they also get their fair share. My opinions are slanted in favour of reason according to what I know. So, if you don´t wanna wind up living a monotonous way of life, find out what you are good at. Bad situations can be averted if you know how to. Lastly, I´d say that even though cushy jobs are no more, you still can get a pretty good one. A job that  is gonna help you grow into person you want to become.
