Don't waste your time with explanations: people only hear what they want to hear.
A key issue in developmental biology at that time was the problem of how cells underwent differentiation, with most workers concentrating on explanations in terms of changes in enzyme and gene regulation.
For a person who grew up in the '30s and '40s in the segregated South, with so many doors closed without explanation to me, libraries and books said, 'Here I am, read me.' Over time I have learned I am at my best around books.
The five steps in teaching an employee new skills are preparation, explanation, showing, observation and supervision.
Time and tide wait for no man.
With all due disrespect...
