You really should stay in your comfort zone.
Yes. Really!
Comfort zones are perfectly fine. Just ask anyone at the top of their field and / or getting what they want from life. They will 100% agree that they’re in their comfort zone!
There’s just one pretty-small caveat. You need to be comfortable, when doing the things that are consistent with what you want from life. If you are, you’d be a fool to leave your comfort zone.
If you’re not getting what you want, and not comfortable enough to do what’s required, it isn’t a zone issue. Blaming the zone is nothing more than passing the buck.
It’s a YOU issue.
Thankfully, that places it fully under your control.
