alt Hacker NewsI'm only good enough to impress people who don't know what a good guitar player sounds like.
My advice to people, which seems to work OK, is just to have the guitar out and ready to play wherever you're likely to be - maybe even in the way so it has to be moved sometimes - and just pick it up and play it as often as possible.
Waiting for the kettle to boil? Play the guitar. TV is showing ads? Mute it and play the guitar. Your partner needs to go to the bathroom before you both go out? Play the guitar.
It doesn't matter what you play, it doesn't have to be good, it can be a random improvisation, it can be scales. Your fingers are learning.
It depends on what your goals are. If you're doing it for fun or as a creative outlet this is great advice. If you're trying to actively get better you won't do it this way after a certain point. You need to be actively practicing and engaging your brain. It does matter what you play and how you play it.
