Or maybe it should be good vs better.
Sometimes better is worse than good but we think that good is enough so we don’t aim for better. The mindset of a Bare Minimum Betty often lies in the good zone.
If you choose to aim for better that could mean a variety of things, a key one being commitment but it’s more than that.
Aiming for better is:
Trying something new that in the words of Seth Godin ‘might not work’
Doing more than you have to
Looking for ways to improve
Offering to help someone else
