It does sound like you set your self up for trouble by doing too much. Very high goals.
I too have done that with our business. We took on more customers than we could handle and pushed our selves with fear of money. Needing to much and not enjoying the moment. Acting like machines. Life just keeps adding more stressors and your tired and wonder how long you can keep it up. Our society suppports some pretty bad habits. I have to find a balance to work at a pace that compliments my ability.
I am so aware of that now! And I'm working on it rather than have everone one else plan my days for me. I like it.
Quality not quanity.
