There certainly is a ripeness factor when it comes to idea suitability and this can be a major or minor influence depending on the situation.
Sometimes ambition is great enough even when finances are inadequate, where just moving a little bit in the ultimate direction (like shipping hardware) is materially out of reach for such an extended period, startup and growth potential can never be realized without the most exceptional source of funds to provide leverage.
This pushes the time horizon further out as it would naturally take much longer to connect with such an elusive benefactor on terms that can truly maximize the performance of the combined resources.
So it seems like a good idea to have ideas that can stand the test of time, the more ambitious you are.
Great advice from pg about tactically limiting the depth to which your full ambition is displayed day-to-day so that rather than pie-in-the-sky being constantly pursued, stakeholder interactions can be punctuated by achievable milestones they can visualize being reached.
In a capitalist arrangement it can come back to the visionary exceptionalness of the capitalist as the limiting factor as to when or if you can bring your full potential squarely within sight.
