Who you were in high school or elsewhere is history. The now presents itself to you as a new beginning. So, begin where you are. Take the next step for yourself. Run to win.
All good athletes train hard.
They do it for a gold medal that tarnishes and fades. You're after one that's gold eternally. I don't know about you, but I'm running hard for the finish line. I'm giving it everything I've got. No sloppy living for me.
