A good question usually. Generally the answer is working hard.
This is never easy. Being creative, that is. We try to never repeat ourselves and this becomes increasingly hard when every day you make something new that you can never repeat! A conundrum, certainly. And getting older each day, we forget some of what we did prior.
We have 2 kids, a white elephant of a house, a needy dog, Argus, and an penchant for watching movies. So it is easy to become distracted. However, we are disciplined. We are completely self-directed. We love what we do, how we do it and who we work with and for. So the answer, in a roundabout fashion is working hard, always. A good question usually. Generally the answer is working hard.
