Nobody Cares Until You Win | Consistent Sai Ep. 02

The fear of what people will think can stop us from starting. In this episode, I talk about recording my first podcast, my old rap song and the freedom that comes with realising nobody is thinking about you as much as you think. Put in the reps. Write the songs. Do the mileage. Make the episodes. Start before you feel ready.
