Downtime
When we are non-focused, without any specific goal, and let our mind wander or simply relax, we help the brain recharge.
Downtime is an unplanned activity that can lead us to many different opportunities. It could happen between activities like when we are waiting for the next class to start or waiting in the line up at the bank.
Downtime is particularly useful when we have come to frustration about something. It leads to creativity and insight. Whatever was the cause of the frustration is solved.
