Every Breaking Wave Lyrics

Cover art for Every Breaking Wave lyrics by U2

I think it's about someone trying to decide whether to stick with something (a relationship) or give up every time an obstacle (breaking wave) is presented. There are always so many reasons/excuses to give up on anything when it starts to get hard. Will you stick it out or head toward shore (safety) on the next breaking wave?
