That happened the night of his election, when he knelt down to receive the blessing of the crowd.
“I’m not like other Popes. I’m much more humble. I’m different. Look at me! Look at meeee! Look at MEEEEE!!!! I’m humble!!!!!”
The best thing the next Pope could do is NOTHING that calls attention to his personality, his humility, etc. And no press conferences, few or no plane trips, etc.
I don't believe there will be a 'next pope'.
