Get Your Timing Right

I had the idea that I would be an inventor when I was 5 years old. Now, 52
years later, I still fashion myself an inventor. After some youthful
experiments, I realized that the key to a successful invention is timing.
Many inventors succeed in getting their contraptions to work, yet most
inventions still fail in the marketplace because the enabling factors
needed for success are not in place when they're needed.
