Man is a generalist. No harm in that: he/she is remarkably adept at adapting and to enhance this process has created a batch of tools which allows him/her to perform to the highest levels.
When push comes to shove, what are the essential Tools of Excellence?
20: The Beanie
For the brain to do its best work it needs to be kept at a perfect temperature. Too hot or too cold, distraction comes into play followed by discomfort as the brain nags us to restore perfect operating conditions.
Have a beanie to hand. In wool they are warm and adjustable. Pulled well down they will help any writer cope in their chilly garret. As momentum is built and a decent dawn is revealed the hat can be pushed back and and a cooled forehead allowed to emerge.
Later as we walk on the beach, switch to one in cotton. A burnt neck is avoided but those rays augmenting Vitamin D can be enjoyed.
