If you want something done, ask a busy person. They're in flight, in flow of scheduling, prioritizing, and completing tasks both small and large.
People with free time will take their time. They tend to lack urgency, focus, and passion. They over think the ask, spending hours planning rather than doing.
Quality of execution predetermines an end product. But so does speed and adaptation. Shipping imperfection and learning quickly from your mistakes is a good way to prepare for bigger outcomes.
When in doubt, keep riding the wave of productivity. Push stuff out there and evolve.
