Zealotry of the newly Fit

I've been having a lot of fun with my increasing fitness lately in climbing and acro-gymnastics. This new good feeling has on occasion turned my my thoughts towards those of the newly converted zealot: "wow, this is awesome, this is clearly better, everyone should do this"
This may be partially true, but for the other part I should probably try to not be a jerk about it.

. . . . .

and I don't have to look very far to see examples that make me think humbly that I have a lot more improvement yet I could do.
