There are five simple steps in building your resilience against burnout.
Step 1: Realize
Sometimes bad things happen. It is not your fault that you are burnt out. It is ok to be not okay.
Step 2: Recognize
Take your time to recuperate. Watch the warning signs of burnout. Take time to think, breathe, reflect upon your experience. See how badly you have been hit.
Step 3: Reverse
Undo the damage by managing your stress and seeking help and support. This is usually the phase that is the most difficult. You need to do loads of soul searching to find out what kind of your personal practices lead to burnout. You need to undo them and replace them with new practices.
Step 4: Resilience
Build your ability to withstand stress by taking care of your physical and emotional health. Exercise. Eat well. Go to concerts and theatres. Enjoy the company of your friends and family. Dance. Find old or new hobbies that energize you.
Step 5: Reconcile
Make the best use of the downtime to try to achieve what is achieve. Make peace with the stuff that you cannot achieve anyway. Life is beautiful!
