I think it helps a lot if you practice a little bit with the tools the
writing system is intented to be written with, e.g. with a broad ink pen or
with a brush. Already within very little time, I'm talking about a few
hours, you may be able to see which letter forms work.

My writing systems got better the longer I used them. I learn them by memory
and then keep practicing. I once had a project of finding out into what my
handwriting would finally evolve if I kept simplifying it. I already had
evolved it into script that were similar to runes, to arabic, to cuneiform,
to lowercase Roman letters, and several more, so I thought there might be a
final simplification (I've always been interested in the reduction of
forms), but I abandoned this project when I saw that there would be no such
final form.
