I make plans. Plans for the projects, costumers, weeks, interns, subordinates. Then make daily, weekly, monthly and yearly reports. Analyze which goals were accomplished and why others were not. Well that is how i work. How i study is different. When i start, my first goal is to study 2 hours for a week then next week 2.5 then 3. 3 is optimal for me. After a month i analyze how i am doing. Am i slow? If so why? Is the study material or the method? Each week i change a parameter to see what is holding me back.

If you make plans and start doing them little by little you get motivated so you make your plans small at first, like waking up before 10 or something.

You need to teach yourself that you can do stuff. In order to do that you gotta start small. After a while you will definetely get a momentum. But if you keep poundering that you need 12+ hours study everyday while doing no study it will just demoralize you.

Think of it like muscle training.
