I prescribe you “The Procrastination Game.” The only way I get things done ever. You have three projects that you haven’t touched in a while. You force yourself to work on one for 30 minutes. The reward for 30 minutes is a handful of M&Ms or other treats you have. After the 30 minutes, asses if you’re still uninterested or the work has reignited the spark to pursue this project. Work on it until you get bored. Now you’re bored, you’d rather be doing something else, say for example, project 2. You are tired enough of project one to work on project 2 in procrastination. Continue the cycle onto project 3. Reward yourself candy or whatever else you like every 30 minutes as you bounce between projects. This is how I manage a semi-busy art commission schedule with schoolwork and music studies. Yes I am dumb enough to train myself to work for treats.
