The first step is to identify your time to dedicate to poker, as you have another activity, what I suggest is to play sit go, which I believe you can play 25 to 30 sits per day. Seek to study, always seek to evolve. If you want, I can review your tournament that you won, if you're interested, just call me in private. The mtts, in addition to having a much higher variance, you have to have a good amount of time available, which I think is not your case, playing sits you can easily achieve your goal, at the beginning of my career I started playing sits, I played sits from 1$, I ended my positive session almost every day (because technically I am much better than the 1$ sit players which is not very difficult kkkk, and because I play with a very small amount of players, that is, very low variance , totally different thing in mtt). So that's it, here's my tip for you. Good luck.
Ahhh man and always take care of your mindset, it's very important that you know how to take care of it, if you don't have a nice midset it will be very difficult to achieve your goals.
