Simple Victories

I like games like solitaire where you put in a couple minutes of your life, and can come out a winner. I like things where you have a simple victory or accomplishment, but you can also throw away the pearl you get from the oyster and have no second thoughts about it. Anything that provides a simple victory is a motivator for most people, I believe, to keep going and take on the harder challenges of life.
You know how easy it is to hit "File", "Deal", on Solitaire when you get stuck so that you can start completely fresh and hopefully have a better chance of winning? Easier than playing the game itself. And yet, in the simplest of situations, I ultimately refuse to do that, even though that's one of the few places in life where I CAN do it, and face no consequences; only possibly another victory.
I hear people talk about how they love math because you're either right or wrong. You don't have to guess, or fumble, and be unsure on whether your answer is good enough. You're either right or wrong. To me, that's the worst possible situation to be in; and yet in games that hold simple victories, you're still either right or wrong. What's the difference?
Math is a "building" tool. Once you learn something and get it right, you learn how you can further use it...and it just keeps on going. Even if you hit those simple victories in math, there's still more to learn; further to go. You put the grain of sand into that oyster, and eventually with enough pressure and struggle you get an oyster out of it...but then you have to start all over and try to create a bigger, more advanced pearl.
I like the games/skills/challenges where you can get the pearl at the end, and then feel accomplished and have no second thoughts when tossing it away. I like the motivation of simple victories.
