There is nothing wrong with being realists. I am a realist a lot of the time. But if you're not careful that can become an excuse for giving up and not trying. The point of the meme was never about chess itself. It was about life goals. I Googled "against all odds" and this picture came up. And I thought it fit the quote pretty well. The template is just for symbolism. No matter how many odds are against you, no matter what objectives are in your way, you can still be the best you can be, you can still succeed.
I am currently trying to accomplish something that a lot of people think I shouldn't even try to do. But it is something I really feel like I need to do. So failure isn't an option, even if there are some odds against me.
