Any experienced guitar players have advice on how to learn better?

I played very little in highschool and now, 15 years later, I have the urge to go back to it. I've been playing for an hour or so most days for the last month which I know isn't a lot but lets be honest, it's just for my own enjoyment, I have no illusions of being a middle aged rock star.

Anyway I was wondering if people had any advice, good resources, sheet music that isn't garbage?

In my position would you go the self taught route or is it really important to have a tutor? I'm particularly concerned about picking up bad technique and then practicing that, I feel like that was a big part of why I gave up in the first place - fucking up the same things no matter how many times I did them because I learned them wrong.

Thanks all.
