At the ACS Careers blog, John Borchardt discusses what he calls "career potholes" — events or behaviors that disrupt one's professional trajectory — and how to avoid them. "Just like potholes in the road, career potholes can upset your mental equilibrium and focus," he says. Since some bumps are generally out of one's control — job loss, for example — Borchardt says it's best to prepare for the worst.
