Work with what exists until what you need becomes reachable.

Waiting until you have what you need means not working, and not working is what usually keeps the thing you need out of reach. Starting with what exists produces progress, visibility, and often the very resources you were waiting for. The sequence runs the other way from how it feels.

Build the version that is possible with today’s constraints. Treat it as a stage rather than a compromise, and let it be what earns you the better conditions.
