I never saw my dad cry. My son saw me cry. My dad never told me he loved me, and consequently I told Scott I loved him every other minute. The point is, I'll make less mistakes than my dad, my sons hopefully will make less mistakes than me, and their sons will make less mistakes than their dads.
When I start working on a batch of tunes - like roughly 10 solid tunes - I always know there'll be another 10 to follow, because for every song I invest a lot of time in, there's another song waiting behind it.
