Theory or Application?

A basic understanding in why we do things provides a good baseline for action, but I find those expounding mostly theory fall short of the actual application of what they theorize about.

Theory refers to contemplation or speculation, as opposed to action.

A classical example sometimes used to explain the distinction between theory and action within medicine goes like this.
Medical theory and theorizing involves trying to understand the causes and nature of health and sickness, while the practical side of medicine is trying to make people healthy.
So the next time you pay to learn something, make sure that you understand that advertising theory doesn't necessarily mean the individual understands how to apply it to practical application.
