[Stefan's Stamina - How does he do it?]

Hello FDR, hope you're doing well.

I'm impressed with Stefan's work ethic. He puts tireless amounts of work every day and the quality is elite. I'm half his age yet wonder if I could keep up.

How does he do it? Has Stefan ever given lifestyle advice with regards to diet, exercise, sleep, morning rituals etc? If so, could you please refer me to the source?

 

Thank you in advance, and have a good day!
