Proper to-do list usage

It took me forever to learn this simple tip:

Use a to-do list app only for things that absolutely need to get done.

Anything else, use a different system for. I use Obsidian. If you don't follow this advice, your to-do list software could get cluttered to the point where you stop using it, then you switch to another and repeat the process.

My favorite to-do list app is Todoist.
