The thing about giving something your all, about holding nothing back, is that if it isn't good enough, you have nothing more to give. If you work somewhere where you're not measured against others' performance but against your own, and you always give it your best in a area where there's no room for improvement, you're going to look like a slacker standing beside those who slacked off early in the game, played with the numbers instead of being honest with them.
I'm honest with my numbers, because only then can I trust them to be honest with me. People aren't like that. I can give everything at face value, and people still play games with me, with their words.
Give me print over verbal interaction any day. Give me hard stats before intrapersonal interaction. Give me something that won't change, regardless how you look at it. Give me a language that won't change its meaning.
Give me a goal to work towards that doesn't change, a set of expectations that remain the same for my tenure, and stop trying to play games with my numbers.
You can look at your month-to-day call statistics and make what judgments you want, but any true statistician knows that any group below thirty is not true to the mean. You can take your pages of fifteen shifts and go fuck yourself, but if you want real numbers, you come see me and my chart of thirty-two months of truth.
