Malachi Thompson mentions Dr. Joan Rosenberg’s in his article about handling your emotions when starting a business.
“the greatest intensity of our emotions lasts for about 90 seconds. Don’t fight what you are feeling. As the energetic sting subsides your mind relaxes, and your brain has a freer capacity to shift into a new gear. Relieve mental exhaustion by also dedicating time-bound expression of your dread, worry and panic. Honor those concerns for a sort time, and those feelings too shall pass.”
