I did not understand this idea until more recently. With a very athletic background, I always thought "Shouldn't I just want to do my best just because" and that is true, I guess I had never met people who really inspired me too. Because there is something about being inspired by the positivity of others that can make you want to be better.
In the past couple years I have pushed myself in my career and in life, and I think in the past this may have been enough. But here is where the people come in and something has changed.
I have met people who make me want to be better not because I want to be the best. But because I want give the best. I want to provide more. I want to learn more.
People who make you want to be better are not the people you are competing against. They are the people in your corner working as hard as they can which inspires you to work harder. Work harder for them, for you, and for those you want to work for.
In life it is so easy to feel defensive and alone, but if you realize anyone can be on your team if you let them and that that puts you in a position to take charge. You find a new strength, on that you one have just working for yourself. And when you find this second kind of strength you wont have time for the people who doubt you because you and the people you surround yourself with will be busy being your best.
So my advise is to find those people in your life because they are probably already there. Share as much of your journey with them. Positive attracts positive. And people who make you feel like your doing your best will help you do even better.
