I think the secret to your success is your positive attitude.
The secret to my success isnt' a postitive attitude. It is from having been raised in a christian farm family. Bottom line, you do what you have to to get by. Attitude has nothing to do with it. Life sucks. You still do what you have to - period. But you do it ethically, put your faith in God, and in a manner in which you are able to look at yourself in the mirror with a clean conscience every day, you do what you have to. How I feel about it is immaterial. The job must be done.
From this standpoint I take credit and blame for what I do and I lay credit and blame for what others do. And I have no compunction about being frank in defending myself or others against abuse. I stand up for what I believe in. And I defend my ground. Getting things done requires no less. Even if people trying to screw you wish to call it whining because they don't want others to listen and get any ideas.
