Burning the candle at both ends, overwork, stress, and self-sacrificing causes us to leak Jing. This kind of lifestyle is not sustainable, nor is it sustainable to sit all day in artificial lighting and live only in the mind, as this will lead to a drawing on and depletion of the deeper reservoirs of Jing. It is important to connect to your will and your Heart’s intent to create a lifestyle where you sustainably use your energy, while contributing to society with your work in a manner that gives you joy and purpose.
A healthy lifestyle is in tune with the elements, and this includes quality sleep and rest (they are different), getting sunlight, time in nature, great nutrition and hydration, time for a quiet mind, a physical practice that is not depleting - and all the things you know contribute to your overall health and happiness.
Remember to laugh and take a moment to appreciate life, daily.
