You need to start where you are, and realize that just doing more things isn't going to fix any holes in your life. If you have a ton of things to do and you are having trouble keeping track of them, then you might have use for a tool.
Separate your work and your life and your ambitions. I'm lucky enough that I can track my work stuff in my head. If it ever gets to where it's too hectic, I escalate to a written task list.
My home life is similar. All of my life context is kept physically. I can see that the dishes aren't done. I can see when I need to take out the trash.
My ambitions, on the other hand, well, I've spent man-years of effort on hacking away at solutions to manifest them faster. I don't consider the time I've spent writing scripts and stuff wasted because I love doing this stuff, it's what I naturally start doing once everything else is sorted. I don't take a 'ship it' strategy to them because to me the point is enjoying the journey, not to get to the end as fast as I can.
I don't have to build a colocated kubernetes cluster in order to host a blog, but I want to. It appeals to my sensibilities to not pay hundreds of dollars for compute when I have a perfectly good desktop machine with lots of its own compute.
I've spent more time on keyboard macros than I'll ever save. But the feeling of power I get from having my world accessible with just a few keystrokes is great. And learning about how evdev and xbindkeys and the like work is interesting as well.
The hole isn't filled when I get to the end. The end is when the hole stops being filled. This is what organization will do to you if you're not careful.
