23 with over 100k student loans to pay

Hi all, I just finished grad school and will be beginning my career as a physical therapist. To begin: No, we don’t make 6-figures starting out. Yes, I’ve thought about this, but it’s what I love to do. I plan on paying 3350/month to go towards my loans until they’re paid off (this is a big chunk of my check, but i want to pay loans back asap). This is my ideal plan, however I know that everything will cost more and more as time goes on. What do you all recommend to begin earning passive income so that I can continue to pay off my loans and live comfortably aside from investing in stock, crypto, etc. I’m in debt, but I am young and want to take advantage of resources that I may not be aware of. Any feedback is appreciated, thanks!
