Just adding to what Chris said as that's exactly true; you gotta put in the work and time.

However, acoustic is 'harder' to play than electric. If you're an experienced player, you simply adjust to the instrument that you're playing. As a beginner or early in playing experience, it's a much bigger thing. Learning guitar already brings its own set of challenges, finding an instrument that's easier to play will make you want to put in the time and 'work'. To be honest, when you enjoy playing, it ain't work.

Because you want to play rock styles and you have played enough to know that you want to continue to grow, the jump to electric is not a bad decision. Easier and it aligns with where you want to go anyway.

Unless you're wealthy (and I figure most of us here ain't), set a budget for a guitar and even a small amp. You can get a lot of guitar without spending $2500 on a Gibson Les Paul...that problem comes later  😎
