We have all heard the question, more than once, “Which came first, the chicken or the egg?” I will avoid evolutionary biology and not attempt to posit an answer. Instead, picture a guy shrugging his shoulders. The fact of the matter is, for most of us, it does not make a bit of difference. However, in many things in life, the order of things does make a difference. For example, if we do not have basic arithmetic skills, it does not seem reasonable to delve into algebra or calculus. Knowledge seems to build on itself. Certain kinds of skills – reading and writing for example – are foundational in nature. Once we have developed those skills, we can use them to develop other skills.
