I see many people, not only real estate, but business in general, who fail to grow to their potential. They have reached a place of comfort and and taken their foot off the gas. The problem with that is you never just coast. You're either growing or dying.
Once you become comfortable, you stop looking for new opportunities. You start to become complacent, stop learning and honing your craft. You start to fall behind your competition. You have pulled yourself out of the game.
One way to grow in business, is to grow in other areas of your life. Constantly put yourself in the uncomfortable position of learning a new skill. Think about the major milestones in your life. Did they come from a place of comfort or from a place of uncertainty. You can never grow from a place of comfort. You will have to put yourself out there to truly reach your potential.
