Play a game with me.

Life is a game.
Specifically, a game of chess.

The goal is to move forward, one step at a time.
Our decisions take us to that step.

Sometimes nothing happens.
Sometimes we gain.
Sometimes we lose.
Sometimes, to gain, we need sacrifice.

Ultimately, the moral of the story is to not regret the step we have taken.

We cannot reverse the progress of the game. 

We can only continue from where we are now.
We can only mourn for our losses, but the game continues.

All I want to ask is, how do you know you have won?
