Spend time with grateful people. Gratitude is highly contagious–that is why I spend time reading Tammy Strobel. You can read gratitude in almost every word she writes. Find grateful people who experience contentment in their lives and spend quality time with them. You can find them online or you can find them in person. But the more you invest your time with them, the more their spirit will become yours… and soon, others will desire what you have.
