Don't waste your time in the race looking back to see what the other guy is doing. It's not about the other guy. It's about what can you do. You just need to run that race as hard as you can. You need to give it everything you've got, all the time, for yourself.
What you focus on expands, and when you focus on the goodness in your life, you create more of it. Opportunities, relationships, even money flowed my way when I learned to be grateful no matter what happened in my life.
I know for sure that appreciating whatever shows up for you in life changes your personal vibration. You radiate and generate more goodness for yourself when you're aware of all you have and not focusing on your have-nots.
