Hi i am 26 years old I've been thinking of learning how to play the guitar since I was in college. i bought this game called Rocksmith hoping that it will help me on how to play the guitar, but i was wrong this game is not for people like me,LOL! i downloaded some DVD's, like Learn and Master how to play guitar, and Learn how to play guitar in 25 days.but the problem here my only free time is on Friday, because i'm here in Saudi and we work Sat-Thursday and there are days that i go home late so i don't have time to pick up the guitar, how long will it take me to really learn how to play the guitar and be able to play some tunes? and whats the best way to do it? should i go like 4 hours a day? sorry for my bad english.
