Why is Time, Money?

Anything that is scarce is a valuable resource. Time is effort, to think is an effort. Waste your time and you will have to micro manage or multitask to catch up. Service providers are paid based on time; by putting thought to action that others could possibly do themselves if only they tried or developed. What wastes time is the fear of not getting it right because one could be ridiculed or cause damage to another or the environment.

Why is time the only thing that limits man, yet man creates more limitations for himself and by that looses even the little time he's got?
