Gratitude is so cool because it sends your brain into a virtuous cycle – good begets even better. When your brain experiences the good from the gratitude, it looks for things that confirm what it is already experiencing. So if you send a bit a gratitude it looks for more.
The brain doesn’t stop there. It send endorphins, dopamine, and a few other things that courage your positive orientation, attitude, and behavior. Hence that virtuous cycle – big payoffs for your relationships, capacity, and confidence.
