When going outside of your comfort zone is perceived as a fun challenge, it makes life so much more interesting.
Why not make going outside of your comfort zone a fun challenge, so that you pursue it more frequently.
An example of this is that initially I would suggest activities that were outside of others comfort zones, and now it’s become a game where they will suggested something outside of their comfort zone.
It’s very rewarding when those around you see growth as something that is truly fun.
