Next, every day make a list of max 3 things from the list (or steps towards completing bigger things on your list) these are your goals for today.
Next you figure out when during your schedule for today you will be doing your 3 things
Before you know it you have gone through all the original items on your big list
The important part is to keep updating your big list so that important tasks never get forgotten.
You write down 3 things you want to achieve or accomplish today. E.g. Do a certain homework assignment, read 50 pages in a book or go grocery shopping. Don't make the tasks too big, split them up into smaller ones.
Fabulous recommends that you use a physical notebook to write your to-do lists. Personally I use Todoist.
Make it a habit that when you wake up, you write down what you want to do today. And keep it to 3 tasks only. If you have extra time you can of course do more things. But focus on the three most important tasks.
Some people also plan out their day by placing timestamps next to the tasks, as a sort of deadline for when it needs to be completed. This way they know exactly what to focus on and can easily get back on track if they get distracted. Personally I don't do this but feel free to try it out.
