A Friend So Dear

Lurking just beneath the surface I bubble up when you most need me You'd love to think I'm worthless Then you're glad there's what to feed me I assume the shape of motivation When you need to be ambitious Though I can make you shake all over Thanks to me, you realize your wishes Without me you'd never make it Through life's thorns and brambles I'm there to push you when you need To take big risks and gambles Please welcome me when I appear Perhaps by now it's crystal-clear ~ My name is fear
