Depends what you class as enough...
I clicked "enough" because my months bills are always covered.
I know what I need to earn a week to stay afloat, and I manage that probably 50 weeks of the year.
Some weeks I have a decent amount left over, sometimes I don't have any.
When something unexpected comes up I can't always manage that week, but sometimes I can.
So yes, I earn "enough", but in some ways i suppose not.

I know that's confusing, but I bet a lot of people are the same as me here.
