The elements of calm are simple:
Control. You have achieved sufficient control over the present and the near future. This can be achieved either through the power to influence results or through indifference to events that may occur regardless of your actions. Control is the antidote to fear.
Acceptance. An intense appreciation of what you have versus what might be nice to have.
Creativity. An ability to look into a confusing or bleak setting and see opportunities for improvement. This can be linked with the assurance that you are capable to seizing those opportunities.
Patience. The knowledge that moving methodically may seem slow but doing so will permit you to move much more rapidly than if you rush past steps and lessons.
Humor. The less we analyze this, the better, for analysis causes it to disappear. Suffice to say, when humor is present you will know it.
