I'm terrible at it too. A lot of it stems from anxiety. Like I would put off my school work because I was scared I wouldn't be able to do it. Same thing now for my work. But some of it is just me being lazy. Like doing chores and stuff, I just don't feel like getting up and doing them.

Sometimes what I do is make myself do what I'm supposed to but give myself a time limit, like twenty minutes, and then I don't feel trapped doing it.
