I've heard it a million times and no it is not true... You aren't born a success. You aren't gifted with the ability to work hard right out of the womb. Seriously, my parents thought I had a learning disability because my work ethic was so poor in middle school. And now I work 12-16 hours a day because: (1) I love it and (2) I have a unique opportunity to try to do something great with my life.
Stop making excuses about being born with an ability to be great or not. Develop habits over the next 66 days and witness the impact you start to make on the world.
