Create a small Todo list of things you plan to do every single day. It should be a small manageable list. The point of keeping it small is to avoid procrastination. Procrastination is symptom of anxiety over tasks we need to do.
So you create a small Todo list and on that list you have something like -
Read x amount of pages of a book.
Do X
Do X
Go to the Gym
Etc. Etc.
Everyday you wake up and try to complete the activities on the list.
Slow and steady. Consistency over intensity.
You'll see that the number of pages you've read will add up very quickly. Just keep it manageable. It's not a competition.
