Query: How contrive not to waste one's time?
Answer: By being fully aware of it all the while.
Albert Camus

To be aware of time it's important to understand your own subjective definition of what time is. I agree strongly with the concept of a physical time and psychological time. I see physical time as an organizational method to standardize our subjective psychological times. There are some personal instincts and patterns that all individuals have, but they may not necessarily coinside directly with everyone elses. I see physical time as a way to understand the relationship of your actions and perception of time with those of society around you. Everyone has an internal biological clock that knows when the body needs to do things like eat and sleep and these needs turn into patterns distinct to every individual. Physical time allows people to recognize the moments that they fufill these needs as well as how the people around them are functioning. With this universal map of time people are then able to correspond their actions.
