I absolutely love Tony Robbins. I have been listening to his audios and reading his books for about 25 years. Nobody motivates me like Tony Robbins, except maybe Zig Ziglar and Les Brown. I was lucky enough to attend his Unleash The Power Within event in New York in 2014 and actually did the fire walk. Yes, I walked four metres, barefoot, over burning hot coals! It was an amazing experience.
So, if Tony Robbins can motivate me to walk on fire, then I'm pretty sure he can motivate you to do whatever you set your mind to.
