How much work is enough to reach my goal

I’m inspired by Brooke and by her way of working (3 days a week).
Here’s the thing: I have the thought that maybe I’m not working enough hours during the day to reach my money goal.
I know that I can measure my efforts by the value or/and the quality of work that is being created but sometimes, I’m still wondering if I’m working “enough”?
How many hours is enough?
I’m even wondering if thinking that thought isn’t a way to buffer from taking action?

I would love another set of eyes on that challenge!

Thank you so so much!!
