Odds of Hanging On
The odds of hanging on are pretty good. The odds get better when you treat any occupational stress problems that come up during your career.
The size of the industry is getting larger, but that still doesn't mean there's room for bad psychologists. You're in the business of helping people; if people are continually leaving your office being un-helped, then you won't be in high demand, and your career may fizzle out. Oh, fizzlesticks.
