If you lack optimism then it’s GAME OVER. 

If you’re a negative nelly and you don’t believe in yourself then you better unplug and shut off the PS4 as the GAME IS OVER for you. 

You have to develop some type of optimism in order to make strides in your day to day lives. I’ve seen it a MILLION times in which all people do is fucking complain and drag others down with them. They think they receive shit luck and everything bad happens just to them. You have to develop a skill that you can take a negative situation and revert it into a positive one. Please adapt awareness of being optimistic because once you believe in being positive, the sky is the limit to what you CAN  achieve.
