If we know what we are doing and we work hard enough at it we can get almost anything to stay. We have to be patient. We have to love it. We have to have an affinity with our subject. Gravity helps, but it helps to have a sense of humour some times too. It's good to be able to put things in perspective. And treats, when we've done a good job, help too.
I am a person who builds dry stone walls and bridges and thinks a lot about how to get other people discovering what a satisfying occupation it can be. I am founder and president of Dry Stone Walling Across Canada www.dswa.ca and an avid supporter of the idea of sharing knowledge freely and learning from others.
