Need management help with organizational behavior/attitudes

If you look at life through a negative lens, I can guarantee negative outcomes. You really do become what you think about. I made a choice some time ago to be positive–not to be a Pollyanna but to be realistic. A positive attitude may not solve all your problems, but it will keep enough toxic or negative people away that it will make it worth the effort. Do you agree?
