Or, a box of chocolates.

Life is like a game of solitaire.

Skill will only get you so far. In the end, it's about the hand you're dealt. If it's a crappy hand, you'll lose. If it's not so crappy, you have a chance at winning. It's not your fault what hand you're dealt; it's purely chance. And you do with it what you can.

You can play as many hands of solitaire as you like, of course, quitting those crappy ones as soon as you run out of options.

In life, however, there are some pretty serious consequences if you choose to end the game.

So you sit, out of options, with your crappy hand, until, I guess, the battery runs out.
