Did you ever have days where you just play like crap? Like, the things that were so easy one day, you find yourself messing up on. I have been having days like these a lot, and it's discouraging me. some people recomended a better warm up and a metronome. I've tried the warming up, and still no results. What do you recomend?

`Bad guitar days` just means you don`t REALLY know what you THINK you know. Forget about warming up, and metronomes, play your favorite songs inside out until you can do it in your sleep. THEN you know what you think you know...
