There's a viral video out there of the end of a UFC fight between Cheick Kongo and Pat Barry. It's a clip I've watched over and over because it blows my mind every single time. Kongo has gotten knocked down repeatedly and not just any kind of knocked down. I'm talking, the man is seeing stars and punching blindly. He clearly doesn't know where he is for a bit of time.
All of a sudden, Kongo's vision seems to clear and he's looking at Barry standing right in front of him. Kongo lands a direct hit to Barry's face then proceeds to go on to win the match. It still amazes me that he kept trying to throw punches even when he seemed totally out of it.
There is a key difference between an optimist and a pessimist. A pessimist looks at the present while the optimist looks towards the future. The pessimist complains about this being a certain way and that being horrible while an optimist looks at their situation and says, "You know, this really sucks...but it won't always be this way. I'll make sure of it." Even when an optimist looks like they're down for the count, they're still throwing punches trying to make some magic happen.
What kind of person are you? The kind of person that looks at a closed door with a scowl or the kind of person that sees that door and tries to bust through it? If you've never tried optimism, now is a good time to start. Just like that UFC fight, things can literally change for you at the turn of a dime.
