I'm caught in this trap where I try to spend as many possible hours as I can reviewing and studying PTs but I think not having a definite boundary has been detrimental. I'm more likely to be fatigued and the quality of my studying drops since I spread my time out so generally. I think I could focus a lot more by dedicating some amount of time to coordinate myself, but I don't know what would be enough. Maybe I think that 8 hours is necessary for example but it turns out I could do everything in 4 or 5. I know this is different from person to person, but I'd like to hear different kinds of approaches. Is there something you've found that works for you?
