You've heard the grass is always greener on the other side. Think about it in a different way though: the grass is greener where you fertilize. Water your own grass. Don't always be looking over the fence at your neighbor's yard. Your business is different from other agents you're competing with. It's even different from other agents on the same team.
From the outside, sure maybe it seems like someone else has an easier time than you. But you don't know the behind-the-scenes and you don't know what it took for them to get there. Also, keep in mind that social media does not equal reality. You know the facts of your own life. Your challenges and your goals.
Everything worth achieving takes work. It's the same with relationships. Marriage takes work but in the long run there's more highs than lows. Put in the work and fertilize your grass.
