Having many projects in progress feels productive, but it often leads to frustration. Nothing gets finished. Everything feels incomplete. Choose one project and work on it until it is done. Then move to the next one.
This does not mean you cannot have multiple projects. It means you focus on one at a time. When you sit down to work, you work on that project. You do not switch between projects. You finish one, then start the next.
This focus increases completion. Projects actually get done instead of lingering in a state of partial completion. You feel the satisfaction of finishing things, which motivates you to finish more.
Choose one project to focus on this week. Work on it exclusively until it is done. Then notice how much more satisfying it feels to complete something fully rather than having many things partially done.
