Most managers were trained to be the thing they most despise -- bureaucrats.
The key to being a good manager is keeping the people who hate me away from those who are still undecided.
I like to call in sick to work at places where I’ve never held a job. Then when the manager tells me I don’t work there, I tell them I’d like to. But not today, as I’m sick.
If I had to sum up in one word what makes a good manager, I'd say decisiveness. You can use the fanciest computers to gather the numbers, but in the end you have to set a timetable and act.
