Abraham Maslow was a psychologist best known for creating his hierarchy of needs. Of the five needs, the first four are referred to as deficiency needs, and are said to motivate people when they are unmet.
One day I was passing through Bird In Hand, and saw one of the hot air balloons filling up as they do most summer afternoons. I decided that I needed a great photograph of it and I was motivated. The light was good, it was warm, and they were launching three at the same time. I was as excited as a donkey on Donkey Derby Day (it’s an Irish thing).
There was plenty of time so I took a few test shots, checked the exposure and the camera suddenly died. Not having the extra battery with me, I stayed to watch for a while, pretending that it was enough just to see three balloons floating into the gorgeous blue sky, but it wasn’t, my needs were unmet.
The fifth need is self-actualization, and he estimated that only two percent of people would ever reach that state.
He is also known for Maslow’s hammer, popularly phrased as “If all you have is a hammer, everything looks like a nail.” Or in my case, if all you have is a dead camera, go home, eat dinner and try again another time.
