Balance is inseparable from cultivating stillness. By balance we mean a quiet sense of happiness in your work and in your life: not needing to achieve all of your goals, just working steadily towards them and enjoying your work whether you accomplish your goals or not is enough. This is balance.
Life is short and we spend most of our waking time working. While we won’t point you to a mathematical chart that directly shows the correlation between balance and success, we can tell you from our own experience that it’s the balance that makes the pursuit worthwhile. Enjoy the moments of your work, your co-workers, and your life. We only have these moments. If you are able to pull off a big success as an entrepreneur, you will realize that the moments that led up to the final outcome mattered more than the final outcome itself.
Try it and see!
