What Do You Do to Motivate Yourself When You Don't Feel Inclined to Study Even Though You Should?

Sometimes I just don't feel like doing it. If I get the books and get started I can keep it up for 2 or 3 hours but no more than that, and I would like to study harder.

Suggestion:

I look for videos or job vacancies for the job I would like to have, then realise how well it pays.

Also, I think about what I could afford with a kick *** job.
