At the end of the day "if you do what you love for living you'll never work a day in your life". I'm guessing you do love your career and seeing as you would put in 60-80 hours of work into school each week doesn't mean your lacking any motivation behind it. I look at it as baby steps, keep working at it with the same motivation and you will reach the goals you want. Anyone can who has the passion for it.

but perhaps you might want to do a bit more math + physics studies (online, books etc..) it helps you with formulas and thinking a different way which helps IMO with programming.

Lastly, use a rubber ducky when programming :).
