I had two problems while teaching myself how to code; I'm not that passionate about it, and learning technical disciplines on line is not how I learn.

I viewed coding as a means to an end. Learn to code-->start a business-->get investors-->pay someone else to code. I didn't care much about what I was learning, only that what I was learning could potentially fulfill other goals. That, in and of itself, wouldn't necessarily deter someone from learning how to code, only...

I struggled learning through on-line tutorials (Code Academy et al). It's not how I learn. That was unfortunate, seeing that coding community spearheads this type of learning. I realized that if I wanted to make it work, I'd have to register for a class. Then I became scared that maybe the struggles wouldn't persist past on-line and I'd be financially committed to it. I wasn't willing to take that risk.
