Definition of the word "FLOW" in Wikipedia

FLOW is the mental state of operation in which a person in an activity is fully immersed in a feeling of energized focus, full involvement, and success in the process of the activity.

FLOW is completely focused motivation. It is a single-minded immersion and represents perhaps the ultimate in harnessing the emotions in the service of performing and learning. In flow, the emotions are not just contained and channeled, but positive, energized, and aligned with the task at hand.

To be caught in the ennui of depression or the agitation of anxiety is to be barred from flow. The hallmark of flow is a feeling of spontaneous joy, even rapture, while performing a task

So,
BE HAPPY IN THE PRESENT BUT WITH GREAT IDEAS FOR THE FUTURE
MOVE FROM STRESS AND ANXIETY TO FLOW

You must have goals, but you must feel happy before you attain those goals.
Keep yourself in flow. Discipline yourself to be happy.

A quick note:
Sometimes you have to "destroy" your life to find the next big thing.
Believe that when you love what you're doing and you have big dreams you'll enter that state of FLOW
