I’ve played guitar for about 5 years and recently I’ve noticed that whenever I play for about 5 minutes, I get burnt out on it very easily. Pretty much all I play is punk rock. Is there any way I can make playing guitar fun again? I tell myself that I’ll lay off on playing guitar for about a week but for some reason I go back to playing guitar everyday even though it’s not very fun.
the second chick is right mate, you really need to play and listen to music of other styles to keep yourself interested. You don’t have to listen to country however… But anyway, learning and playing different things can really help you get more interested in your instrument and also get alot better. Try learning a bit of lead guitar too, because improvising leads is alot more fun than hammering out power chords all day long – trust me. My last peice of advice is to change your strings and clean your guitar up real nice – nothing makes me want to play less than when i have shitty, rusty strings on a grimy neck. Give your axe some tlc, learn some new and more challenging things and you’ll get back into it in no time 
keep it real mate and stay true to your music
