Thanks for the question Rebeca.
In my mind, flow and momentum are different.
Flow state is a period of deep concentration. It doesn’t last long. Anywhere from 25 minutes to a few hours (I’m happy to be proven wrong here).
Momentum is when you’re so invested in something that going in the opposite direction has become very difficult. Moving forward happens more easily and at a better pace.
Being in flow state frequently can definitely help build momentum.
It’s like pushing a boulder down a hill. At first, it goes slowly, but as it goes more and more down, it goes faster and faster, to a point where stopping it becomes much harder.
