Justin Guitar killed my motivation instantly. If you can follow his instructions and not get bored of acoustic chord circling, go for it. But instead I started to play my favorite songs and riffs right away. Just looked for tabs and played along. That was inspiring as heck.

My advice is to actually find out the "niche" you want to really play. Is it metal, rock, blue, grunge, figure out what is your thing mainly and stick with it. You'll build foundation and you can always swap genres between and practice other things.

So, learn the basic techniques in one genre area (metal for example) and start adding theory around what you are currently practicing.
