Do first things first, and second things not at all.
Peter Drucker
“The ability to set priorities, focus on them and not deviate may be the most important skill for success in life. The quote from Peter Drucker was written in the context of talking about business efficiency but can be applied to any field. With limited time and energy that is available, there are only so many things that can be done – no matter how many time management skills you learn. And because not all things get you the same return on investment it is important that you only do those things that are the best investment of your time, energy and also money.”
