Discipline is finite. Excitement is infinite.
"Discipline" is like "cost-cutting" — a subtractive approach that can only go so far and, if taken further, undermines and destroys the very thing you're trying to create.
Excitement is like investment: it's additive, it grows, it expands, it builds more potential, and spurs more creation.
Minimizing loss will never take you as far as maximizing potential.
Weeding is necessary, but it won't grow flowers.
