Freud once said that the adult needs acquire two basic skills in order to be happy- the capacity to love, and the capacity to work.
I would go one further. I would add gratitude to the list.
A toddler can love. A teenager can have a great work ethic.
But gratitude takes A LOT longer to learn. It takes most of us to reach middle age before we’re even close.
You want to be happier and more successful? Try gratitude first.
