Brene Brown has actually researched gratitude. In The Gifts of Imperfection she explains what her research has revealed, "When it comes to gratitude, the word that jumped out at me throughout this research process is practice. I don't necessarily think another researcher would have been so taken aback, but as someone who thought that knowledge was more important than practice, I found these words to be a call to action."
Knowledge is helpful but all the knowledge in the world doesn’t matter if you don’t put it into practice. Gratitude takes practice. How do you and your children practice it?
