Triangulating
Understand the manyfold relationships between colleagues. Assume there is/are hurt interest, ego, and insufficienty handled emotions behind all deeds at work. Try not overestimating your current and future position, be that indispensability, control, personal network, seniority, charm. Don’t mix your work persona with yourself. Have a plan B (and C) in your drawer in any case. Assume no everlasting friendship, trust, interest of others at the workplace. Let go of status and enjoy freedom.
