This might be an unpopular opinion but the jargon to 'left our comfort zone' is a very missleading jargon by many motivator, I know many people that 'left their comfort zone' in the meaning of leaving their regular job to chase their passion, or to become entrepreneur or some other stuff. Most of the failed and regretting their decision to leave their comfort zone.

I think what could be better phrase is 'expanding our comfort zone' if we are comfortable become an office employee we shouldn't leave those job, but maybe we can start small business or trade crypto in our sparetime, if we could succeed doing both we can have two 'comfort zones' and if we failed we will still have our previous comfort zone.
