Flow

Flow is a very interesting concept. And as usual Wikipedia to the resuce if you want to make yourself familiar with it:

With flow the psychologist Mihaly Csikszentmihalyi names the feeling of complete and energized focus in an activity, with a high level of enjoyment and fulfillment.

Although with the day to day living I often forget this, but FLOW is my target state of being. The thing I strive for being in. If you are in flow, you are fulfilling your own potential.
