Glad to hear you're quiting gaming and sharing your progress. I wish you the best of luck. Know that we're here for you whenever you run into trouble.
I don't want to be negative, but 10 hours seems an awful long time to grind out studying, even with breaks, assuming you're coming from minimal/no studying.
Do you think this is something that you can realistically keep doing for extended periods of times (weeks, months)? If not, I'd suggest starting with setting the bar a little bit lower (and then maybe progressively increasing your study time over time?). It's my experience that setting goals that are too ambitious/unreal is pretty much setting yourself up for failure.
Again, I'm really just trying to help, no offense meant whatsoever. Maybe you're a guy that can actually manage to study this much, then it's all right.
Lastly I'd like to recommend Marty Lobdell's study less, study smart video, which focuses on attention span and teaches you how to take the get the most out of your study session by incorporating smart short breaks. Should you not have time to watch this lengthy video, Thomas frank has made a summary video on it.
Hopefully that's a little useful to you. Good luck with your studies man! You can become whoever you want to become!
