When you hit burnout, you become numb to the world; it’s difficult to feel joy and gratitude, which is what keeps you fueled in the face of challenges. So recovery means getting adequate rest and reestablishing joy to your life.
While recovering do things that make you happy, rather than things that lead to a sense of achievement. The former feeds your soul and the latter your ego. Also,get an accountability partner to encourage you to follow your impulses and do what makes you feel alive.
