For those that learned development mostly by themselves, was it a one time achieved journey or did you gave up several times?

I'm in this situation in which i have started and progress until certain extend around 5 since I started back when I was 24. I'm now 30 and thinkig to start again.

A combination of hard to understand concepts, feeling stupid, progressing without really understanding what came before, and being generally overwhelmed with jargons I think caused me to quit before.

I wonder, should I even continue? Is this just me or has this happened to anyone? How often does this happen, if it does?

Thank you
