You're behind. So what?
"Quitting merely because you’re behind is a trap, a form of hiding that feels safe, but isn’t. The math is simple: whatever you switch to because you quit is another place you’re going to be behind as well."
—Seth Godin
Yet another truth bomb from Seth Godin.
You are always behind so using that as the primary reason to bail on something is just an excuse. Try to get to the heart of why you don't want to continue so you can decide if that is in fact the best thing for you moving forward.
Don't fall for the trap.
