When to quit.

When you start reporting to your paycheck.
When the only thing you watch at work is the clock.
When your pride asks you for a golden handshake.
When you begin sleeping with the mistresses of doubt.
When you enjoy going for a swim in a pool named self-pity.
When your fellow earthlings make you feel like an Extra Terrestrial.
When the dismal present clouds the brilliance of your glorious past.
When you want to look taller than the man in the mirror.
When your tired soul craves for a new body.
When you have one last thing to prove.
