For the first few months of this, my health declined. I was getting burned out. Couldn't sleep and my blood pressure when way up. Much stress.
I treated each day like it was the gun lap in a race. You can't go at the pace indefinably. Impossible.
I realized this thing is a marathon. I had to practice self-management. Everything in balance.
This thing requires much work, yes. But don't neglect the other important things in you life.
Taking time out is wise. You come back better for it.
