You should look up the popular YouTuber &amp; tech CEO &quot;Casey Neistat&quot;.<p>He proclaims in his daily vlog, to regularly getting 4-5 hours of sleep.  On top of that, he runs 8-14 miles (at a sub 8 minute pace), nearly every day.<p>On top of that, he has a new born, and just launched a thriving tech company - Beme.<p>I saw a post somewhere that suggested he is likely using modafinil.  I wonder how many of these uber-successful people, are using modafinil to shorten their sleep cycle?
