Paul also tells you to get out of the bedroom and play guitar with humans. Don't worry so much about mistakes and play through them. Watching others play live gives you insight into the little details of how others play on the fretboard and pick. Jamming with others will automatically take your playing to a higher level if you play regularly. Not in the basement or the bedroom by yourself.
By learning songs to play with others onstage, makes you accountable. What? Can't handle the pressure, then stay at home forever. I swear though, Paul gets players out of their shell to play onstage and become better players and people. By being accountable as a player you learn new songs, get better technically and better players will want to play with you and have you on their bill as an opener.
How does that grab ya? Sounds pretty good to me!!
Just get up onstage and play something you know with a band at a jam session in your town. Afraid of making mistakes? We all do. Even Hendrix made mistakes. I should do an interview with Billy Cox his bass player from " The Experience". He'd be able to tell you that. I'm leaving you with a Paul Gilbert video on why you need to get out of the bedroom, and the incredible benefits of playing live and with others. You won't regret playing live man.
