Flow Experience

This is a state of mind when you are totally absorbed in a task deep concentration and commitment. A scientist may experience the flow state when is totally absorbed in a research project. During a flow experience, you often cease to be aware of anything outside of what you are doing. Self consciousness and self-doubt disappear. You are likely to lose all awareness of time. Flow Experience is exciting and fulfilling, a reward in itself.

Feeling good helps us focus and persevere at tasks, because enjoyment has specific physiological effects on our brain. Any mental activity that feels good to you is a reward and will induce positive changes in the brain, ranging from the release of natural opiates to the consumption of more brain-enhancing oxygen and nutrients.
