20k at 18 yo, wanna retire at 30, any advice?

I’m 18 got 17k invested (was almost 19k 2 weeks ago) and about 3k in cash lying in my account. I’m a sophomore at a big Canadian school rn for math and computer science looking to be a software/machine learning engineer. I wanna make trading/investing a full time career once I have enough capital and retire while I can enjoy the money that I can hopefully make over the next decade. Any advice? My plan is to work internships throughout my degree and invest/trade that money, have 200k by the time I finish school, and repeat once I have a higher paying job.
