I began learning on a cheap acoustic that made it incredibly hard to play, but I never knew any better.

Many years later, I was given a nicer acoustic and I realized how much easier it was to play. Suddenly the F chord wasn't such a monster to hold down.

I feel like the cheap acoustic absolutely stunted my learning, and possibly caused me to pick up bad habits. But I still have it cause it was my first guitar and kinda like the sound of it. But holy shit, it's still hard for me to play it
