You need to balance what you need to get done with your natural curiosity. Separate them out and make sure both happen.

1. Work out what material you need to cover on your required studies.

2. Break it down into shorter, manageable bits. A chapter per week, perhaps.

3. Make completion of these bits concrete, so you know you are progressing (and not just reading). Completing the exercises, perhaps.

4. Break down the bits even further, so you can plan them across days.

5. Every day at the same time, start working on these bits.

6. When you finish your bits for a day, stop working. Your reward is the rest of the day to learn about whatever you feel like, guilt-free.
