Having trouble starting something?

For example, if I have to do homework or have to go to bed earlier or generally have to do duties, I can hardly persuade myself to do it because I would rather watch Netflix lying in bed or something

how can I get myself up to do my duties and then free time

This is completely normal

Write down everything you need to do each day and chop it off. I know from a friend that helps. Or tell yourself: "First I do this and that, then I can reward myself." At first thought nonsense. But it works
