Whenever I think of them, I never am by my guitar. It usually starts with me puttin words off the top of my head to a melody. Then I will think the song sounds cool in my head, and I start humming guitar fills and riffs that go with it. Before you know it, I'm running around my house singin all this random stuff while my family looks at me like I'm a spaz.
O and then I put it on guitar.
There are only two important things in life - There's music and theres girls, not necessarily in that order....
