CAD is a bit like programming, there’s a lot of ways to do any given task. That can make it tricky if you are doing some tutorials that use one workflow, and then start doing tutorials that use a different workflow.
If you want to learn it, do yourself a favor and take time to find a tutorial that goes from start to finish doing the type of project you want to do so you don’t get frustrated when you get midway through.
Like others said, if you are used to doing something in a different CAD software, you might find that the same workflow is clunky in FreeCAD, but if you start out with a workflow that works well in FreeCAD, you are fine.
In my experience, it’s usually a term used to sell you something. Often, it’s a ploy to get you to shell out the money for a luxury good under the guise that it’s somehow good for you.
If a therapist is telling it to you, it seems a bit lazy to me. Really, i think they should be saying something along the lines of “make sure to keep some of your time intentionally set aside to do things you enjoy”.
