if I zoom out I see my list of uncompleted projects so much larger than my completed projects and I get sad, but no worries, I'm not going to stress myself about it. It is not possible to do it all.

About doing many things at once, I try to avoid it now. And focus on one by one. It turns out our brain is bad at multitasking. When we switch between tasks, we need time to refocus. Multitasking is only good when you can do one of the things without thinking too much, like automatically.
