One thing that people often overlook, especially if you're an adult learning a new instrument, is to HAVE FUN! It sounds so obvious, but I see so many adults approaching it the same way they would approach work. They "suck it up" and practice sh!t that brings them no joy. This is the easiest way to lose interest. Kids, on the other hand, are impulsive, so when they learn something, they are basically just pleasure seeking. They "play," in the literal sense of the word.
With that in mind, add structure to your sessions and set goals. For example, I LOVE playing the practice pad and soloing on the kit. And within my pad session, I LOVE speed drills. So, I basically use that knowledge and apply a routine "on top of" the things I actually enjoy that also improve upon the things that I want to improve upon. I set goals, and I track progress.
Now to your question. I would recommend seeking things out that you actually enjoy or things that you find interesting, like I mentioned earlier. Build your bank of "fun stuff." Listen to tunes and watch videos.. when you find something that you like make a mental note to learn that thing. Then, take that to your practice sessions. Don't forget to listen and watch to all kinds of different styles and genres... build a broad spectrum early on, and then you'll have tons of stuff to draw upon when you need fun material to practice.
Good luck!
