Many employees struggle to be perfectionists on the job, which can trigger a cascade of anxieties, according to the Harvard Medical School.

"The core of all perfectionism is the intention to do something well," says Dr. Jeff Szymanski , an associate instructor of psychology at Harvard Medical School and executive director of the International OCD Foundation. "If you can keep your eye on intention and desired outcome, adjusting your strategy when needed, you're fine... But when you can't tolerate making a mistake, when your strategy is to make no mistakes, that's when perfectionism starts veering off in the wrong direction."

In its most severe form, perfectionism can leave you unable to complete any task for fear of making a mistake, reports Harvard Medical School.

To help you prioritize the projects and activities that mean the most to you and keep your personal strategy in line, Dr. Szymanski has shared the following exercise:

What do you find valuable in life? What would you want 50 years of your life to represent? If that seems overwhelming, think about where you want to put your energies for the next five years.

Think about your current goals and projects, and assign them priorities. Use the letters "ABCF" to help you decide where you want to excel (A), be above average (B), or be average (C), and what you can let go of (F). For example:

• A (100% effort): This is reserved for what's most important to you. For example, if your career is most valuable, your goals might be to impress the boss, make sure clients are happy, put out good products at work.
• B (above average, maybe 80% effort): Perhaps you like playing golf or tennis or want to learn a new language. You enjoy these activities, but have no plans to go pro.
• C (average effort): Perhaps having a clean home is important, too. But how often does your home need to be cleaned? People aren't coming to see it every day. Could you just clean up on the weekends? Or focus on a few rooms that get the most traffic?
• F (no effort): Time-consumers that don't advance your values or bring you pleasure — for example, lining up all your hangers or folding all your clothes in a specific way. Do you have any tasks that, upon reflection, don't really matter — you've just done them one way for so long that you're on autopilot? These deserve to be pruned.
