gettyYou finally take the vacation. You come back feeling re-energized. But just two weeks later, you’re depleted, checked out and dreading Monday almost as soon as the weekend begins.Most people respond to burnout the same way. They take time off, set boundaries and download a meditation app. But researcher Barry Farber identified three distinct types of burnout, and what works for addressing one type can make another significantly worse. If you’ve tried the standard advice and feel stuck, you may have the wrong diagnosis. Farber identifies three varieties of burnout:1. Frenetic burnout hits the ambitious overachiever who responds to stress by working harder. You put in more hours, try harder and keep pushing through. Working harder stops being the solution and starts being the problem. A vacation doesn’t help much here because the anxiety driving the overwork is still completely intact. What you need to do first is confront the fear underneath the busyness: What do you think will fall apart if you stop?2. Underchallenged burnout looks like laziness from the outside. But the real culprit is tiresome, repetitive work that offers no engagement. That kind of boredom can wear you down just as much as overwork. The solution isn’t rest. It’s finding work, whether in the job you have or in a new one, that challenges you and gives you purpose.3. Worn-out burnout happens when you work in an environment where your effort never seems to make a difference. Over time, you stop trying. You start missing deadlines, dropping the ball on commitments and struggling to care. Again, rest won’t fix this kind of burnout. Finding small opportunities when your effort produces a visible result can help, and use those moments to rebuild your belief that what you do matters.Burnout is treatable, but only if you’re addressing your strain of burnout with the correct remedy. Start with the diagnosis, and the right solution becomes obvious once you know what you’re dealing with.This is a published version of Forbes’ Careers newsletter.

I discussed the insights with Forbes careers editor Anjelica Tan.Anjelica Tan: Why do you think having one mentor is the wrong strategy?Andy Molinsky: We’ve been sold a particular image of mentorship: one wise, well-connected person can answer your big career questions, open doors, give honest feedback and help you navigate office politics. That person almost never exists. Most professionals spend years looking for this specific type of mentor, and their development stalls in the meantime.What advice do you have for professionals looking for career guidance?Build a developmental network. Think of this as a personal board of advisors. It’s a small group of people who together cover all the bases that one mentor rarely can. Research on mentoring backs this up: Professionals with diverse mentoring relationships tend to advance faster and develop more fully than those who rely on a single person for career advice.You identify five specific mentors. Which one do most people neglect?The Honest Feedback Provider. This is the hardest role to fill but also the most valuable. You need someone who directly observes your work and will tell you the unvarnished truth about it. Think about the last time someone gave you feedback that stung a little. That’s what you need, not someone who just softens everything to the point of uselessness.Which mentor do professionals most often underestimate?The Political Advisor. Every business or institution has an official org chart and an unofficial one, and most people only know how to read the first one. A Political Advisor will help you navigate the second one by pointing out who makes the decisions, whose opinion moves the room and which battles are worth fighting. People often treat this role as a nice to have, but it’s essential.What is the first step in building this personal network of mentors?Audit who you have in your corner. Map your relationships against the five roles and figure out which ones are covered and which ones are empty. Most people are surprised to discover they already have two or three of these connections. Be intentional about filling the other roles and engaging with each of these mentors.TOUCH BASEgettyNews from the world of work.
