Honestly from this point onwards just go read the following two books "Learn More, Study Less" by Scott H. Young and "The Seven Habits of Highly Effective People" by Stephen Covey and implement those points within your life.
Whatever field you end up choosing, it doesn't have to be very commonly believed to be great, put time into it. Do your research on what it requires to be great within it, implement those. Search how it can be related to machine learning and AI… then start working on gaining knowledge and applying your knowledge in both that field and the machine learning aspect of it. The second aspect of your field can be important in two ways. Number one being how our world is becoming (do a little bit of research and you will realize just how much we as humans are trying to develop every field towards that aspect). And number two is if you want to go into the research aspect of your field. It's literally like being a scientist (well necessarily a researcher) in your future field. And it's pretty cool you get to enhance and improve the field you work in.
Now all this might seem a little out there or others even yourself might think of yourself as delusional for wanting something so far fetched, but believe me love, you got this. Put in the work For the next 3-5 (maybe even 10) years and I promise you, you will be one of the greatest individuals within your world. I hope to see you then.
Don't give up or think your brain can't handle the hard statistics, knowledge and whatever else that will come with the life that you will choose.
