Now part of a massive field of research from neuroscience to positive psychology, physical and sports medicine, peak performance, also known as "being in flow" has several undeniably pleasant and productive characteristics:

Complete focus on a single task or activity 

In a world where multitasking is draining and our attention is being paid for by countless digital distractors, attention is the real currency, the ultimate energy.

Serenity 
The flow state is achieved when the brain is brought to produce a special balance of neurotransmitters, namely dopamine, endorphins and anandamide, which together form a literal cocktail of inner harmony.

 Loss of self-consciousness
The attention in the state of peak performance and flow turns away from the self and is instead solely focused on the task at hand. The absence of ego simplifies the ability for the brain and body to perform optimally.

 A feeling of complete control over the outcome
Combining focus, serenity and the absence of self-conscious self-evaluation, the feedback cycle to the brain happens at lightening speed, and complete control over the outcome feels certain.

Once achieved the experience of being in the zone feels:

• Effortlessly intrinsically motivating
  
• Timeless
  
• And "so enjoyable that people will continue to do it even at great cost, for the sheer sake of doing it" - Mihalyi Csikszentmihalyi
