I’d say yes, as this is what i’m currently experiencing (by comparing myself to others). I’d agree with @agamemnonymous@sh.itjust.works’s stance. If you’re not trying to improve and just bashing yourself, you will go down a spiral of misery. I feel like the self-improvement part requires some balance though. You can use this comparison as a source of intrinsic motivation, but you need to keep it from becoming too much to where you become demotivated, keep telling yourself that it is possible, that you can do this.

yeah, makes sense. The cynical part of my mind also led me to your 2nd explanation. :)

I’d do a PR. Although I would understand forking if the project maintainers wouldn’t merge a PR. (or create an issue (for the fix/ addition) if the README says that it’s an option)

I’d agree that blender is very good. I find that it would be more suited to static stuff and renderings, as well as animations. FreeCAD is more like the commercial CAD software you’d find (Fusion 360, Solidworks).

On the topic of blender, It has some amazing features, and I am amazed at what people do with it (I also find it a bit tricky, but I probably just need to put a few more hours into learning)

If you mean CAD, I found that FreeCAD works nicely as a parametric 3D modeler with some nice macros and addons, with the perk of also running on Linux
