The famous guy who walked on water didn't normalize it as a means of transportation. He in fact borrowed a boat on his next trip and the next trip and the next.
Thinking about it critically, the easy religious answer is, he saw they lacked the faith to do it like he did...
But the fact is, our life's mission isn't about stardom, self aggrandizement, being hero worshipped aka Celebrity or money but impacting lives and finding solutions for the collective. A boat would carry and empower more people than a solo show off of greatness. Any way you look
...at it. O ye of great faith, while ye drive for excellence & great achievements, be mindful not to gas light the humans God gave to you and put around you.
