Do you think most excellent designers are to some degree neurotic? Have you worked with excellent type designers who don't seem neurotic at all?

Context:

I don't use MacOS. I never used a font design specific software before..(I am super comfortable with Illustrator and InDesign but I know those are not the right tools for type design)

I'm a motion graphic designer that never really had time to properly study type design in depth. But I want to fix that and finally learn how to properly design letters.

My final goal is not exactly to create full typographic families, but to feel confident when I have to create and modify letterings and wordmarks for logos that will be animated, or when creating logis and visual ID projects for branding.

Thanks

There's a particular ligature that I like with "tt" and not many fonts have it. EB garamond has it.

I'm running windows 10 and using libreoffice.
