Some ideas sound logical right from the start. The wheel and fire were obviously great concepts from the get-go.
But I wonder who first watched a chicken lay an egg and said, "Hey, let's eat that!" Yuck! That was probably met with some skepticism. At the time, no one had visions of fluffy chiffons, lofty meringues, yummy omelets, or delicate soufflés.
New ideas always encounter criticism and opposition. But remember, all great ideas start in somebody's basement with one man or woman with a vision. They key is to believe in yourself and persevere. So trust your crazy ideas. They could change the world!
