This is a great Ted.com talk! Dan Gilbert discusses each of us has the power to create our happiness and it does not come from the outside world. I love his summary:

“The lesson I want to leave you with, from this data, is that our longings and our worries are both to some degree overblown, because we have within us the capacity to manufacture the very commodity we are constantly chasing when we choose experience”

He discusses a study they conducted where when people were given a choice of a painting and one group could come back and choose a different one, another group could only pick once and then keep it. The happiest group was the group who did NOT have the choice to return/to make another decision. They decided to be happy with what they had instead.

Choose to be happy today :)!
