The human brain can be compared to a pressure cooker. It works to maximum potential when the pressure is optimal. A pressure cooker pushes the limit of the boiling point of water from 100 Celsius to a higher value. Likewise, pressure pushes the capability of the brain. An example that everyone can relate to is learning one day before the exam so that we can quickly grasp the topics for the entire year within a few hours.
The pressure cooker has mechanisms to reduce the pressure if it goes beyond a value. If it is blocked, then the cooker will explode. Likewise, we need to find a mechanism to release pressure like listening to music, reading, walking, etc.
God changes caterpillars into butterflies, sand into pearls and coal into diamonds using time and pressure. He’s working on you, too. — Rick Warren
