That is definitely it. I've been playing guitar for years and when some friends tell me how I was born to play because I'm talented, I tell them it's not like this. It actually makes me feel bad. It diminishes all the time that I spent practicing to get better, trying to learn new things, listening and improving my playing.

It's the same thing for almost everything you decide to do, if you take the needed amount of time to practice something every single day, eventually you will get really good at it.
