This is not an uncommon issue these days, particularly with highly capable people. There is so much to be done! And so much that can be done. And when you're highly capable and want to serve, burnout can be an ongoing concern.
Some of us work until it hurts. So, do we work until we burn out--until we are lifeless and need help ourselves--or do we set a pace that nourishes us and what overflows is what we can contribute to the world?
Looking to nature, it is true that heroic efforts are needed on occasion, but, if a natural system is in constant need of heroic efforts, then it is not sustainable--much less does it flourish and thrive. And, it will most likely die. But, if we look at the principle that life flourishes when conditions are right, then we can focus on creating the conditions themselves that will bring life to vibrant strength.
I'm reminded of the difference between eating a breakfast full of sugar or caffeine--sure I'll get a good boost of energy, temporarily, but most likely, I'll crash soon after and be even more tired than before. And I could continue to boost my energy with these temporary fixes, needing more and more to get the energy boost, but eventually I will crash in utter exhaustion.
On the other hand, a truly nutritious and steady diet of lentils, rice and a seasonal vegetable for breakfast creates a dependable and unshakable energy that enriches me until lunch time. Particularly if I don't over eat, which taxes the body more than necessary.
I'm also reminded of the 70% principle in Qi Gong--basically to do the posture at 70% of my capacity, with the understanding that striving for 100% creates tension and stress in the body. This is longevity built right in, just like the nourishing breakfast.
If we'd rather be flourishing instead of hurting, the invitation is to cultivate the conditions that help us thrive. For me, it is when I'm well rested, well exercised, at ease in my mind, not rushed, and doing something I truly love. I particularly thrive when I get regular periods of connection with nature, which is why, weather permitting, I do my QiGong practice nestled under the tall conifers in my backyard.
When are you at your best? What makes you thrive? If you don't know, or are at the stage of exhaustion, try rest first. Extended rest, if possible, to give the nervous and other body systems time to reset to a state of balance and health. From there, begin an adventure of exploration both inward and outward to see what conditions are necessary for your blossoming.
