Quote from : Slack: Getting Past Burnout, Busywork, and the Myth of Total Efficiency Book

Managers who inspire extraordinary loyalty from their people tend to be highly charismatic, humorous, good-looking, and tall. So, by all means, strive to be those things. If you don't feel sable to improve any of those factors very much, you might consider holding on to your people by designing some slack into their lives.
