How to Overcome Lack of Motivation in Life?

For school, I have 0 motivation to do my hw. But I just do it anyways like I'm a zombie. I create schedules for my week Mondays, I do Spanish HW, Clean any trash in my room, Wash my Hair, and exercise. I put alarms for all of these things and just do it without thought. Whenever it's time for me to do something...if I'm sitting down or laying down I won't even start, so I force myself to stand up and do a lil jog for an ounce of motivation. Then go into zombie mode Tuesdays: I'll focus on a different Hw, focus on skin care, and clean off my bed because throughout the week I pile things on my bed. I have a white board and. Color markers... I create a colorful checklist, if I complete a task or at least try, I color it red or green. If I don't do it at all I use black and keep a score.
