Constraint – Growing a business vs overeating

My goal for 2019 is to grow my business, but my desire to stop overeating is also competing for my attention (especially since buffering/overeating come up a lot when dealing with my emotions associated with growing a business). I listen to Brooke talk about how she overcame her desire to drink, yet she was working on and growing her business at the same time. This doesn’t seem like constraint…so how do I balance the two goals (business vs overeating) in a way that is constrained?
