Would they make it worse than watching ads?

It depends if you’re using them all. Systems where I have lots of applications installed (especially graphical ones) will have lots of packages, my bare-minimum container hosts will have few. I think there’s also an element of selection bias here, because people posting screenshots of neofetch on their system are also likely to be people who intentionally run very minimal systems focussed on minimizing the number of packages so they can brag about it on the internet.

TL;DR - the right number of packages to have is as many as are required for your computer to do what you need it to do, and not too many more than that.

Something I’ve found very helpful is time tracking. I have an app on my phone that is always running a timer where I input a task and a project (basically a category for the task). What this has forced me to do is to consciously decide when I’m doing a thing, and it acts as a kind of lightning rod for my attention. When I start a new task, I need to decide that is what I’m going to do and put it into the app, and if I find myself drifting from the task I must either stay focussed or decide that I’m not able to focus on the current task and instead focus on what is distracting me. It helps me remind myself that “now is the time for X, not for Y.”
