I could never do it. My soul wouldn't allow it.
I could never turn my back on art for the sake of financial security. Could I have chosen a more lucrative major than journalism or English? Yes. But I could also be dead inside. You see that soaked cardboard box in the gutter? That one. It's perfect.
On a completely unrelated note, two songs I've discovered that give me that something's-on-the-horizon-now-go-grab-it feeling:
Spoon- Don't You Evah
O.A.R.- Love and Memories
Highly recommend them.
