What haunts you is real.

“It may be that what you could be haunts you. It is real. It is a weight you have to carry around. Each failure to become, to be, is a weight. Each state you could inhabit is a burden as heavy as any physical weight, but more so, because it weighs on your soul. It is the ghost of your possibilities hanging around your neck, an invisible albatross, potentials unknowingly murdered.”
