Inventors of wonderful new things are often surprised to discover this, but you need time to get any message through to people. A friend of mine rarely does anything the first time someone asks him. He knows that people sometimes ask for things they turn out not to want. To avoid wasting his time, he waits till the third or fourth time he’s asked to do something. By then whoever’s asking him may be fairly annoyed, but at least they probably really do want whatever they’re asking for.
