I was into guitar heavily when I was younger I started at 12. Then I felt unfulfilled with it cause nobody taught me and had to do it myself. So it was frustrating. Either way life got tough and I stopped playing as much cause I couldn't get to the level I wanted.

Then my mom died at 17 and I didn't touch it almost at all for almost a whole year. Only here and there. Then after that I slowly got back into music. But I was older and started being smarter about my approach. I wasn't so much better just wiser to things, and not as self critical. It made me happy and wanted to be better so I read up on all ends of it, got books, did some theory. And have taken a couple lessons from teachers when I could afford it.

The best thing I could say is when things seem tough try drawing new places and sources. I love certain bands but listening to them doesn't inspire me. Sometimes it's something as simple as seeing someone redo a video game song on youtube to go "Hell yeah!" And if you keep reading, listening, or watching what you can and have an open mind you'll always have fresh material to keep you inspired and interested.
