I've always been a very careful sailor. I know, me and being careful - doesn't really sound right, does it? But when I sail, I take it seriously and take along spares for everything. You have to be careful when you're 1,500 miles from land. There's no one you can call. You're on your own.
If the Spray discovered no continents on her voyage, it may be that there were no more continents to be discovered. She did not seek new worlds, or sail to pow-wow about the dangers of the sea.
This is largely the methodology I've used throughout my career - that is, starting with a question as to what might be the properties of a set of compounds that could be invented which were unusual and unpredictable. Many times I've felt a bit like Columbus setting sail.
If a prospective Presidential approach can't be explained clearly enough to be understood well, it probably hasn't been thought through well enough. If not well understood by the American people, it probably won't 'sail' anyway. Send it back for further thought.
