Engineering is treated with disdain, on the whole. It's considered to be rather boring and irrelevant, yet neither of those is true.

There's nothing wrong with things taking time.

Exactly 5,126 attempts to make the first bagless vacuum cleaner were failures-some catastrophic disappointments, some minor defects. It took 15 years. Prototype 5,127 was the success ... Failure is painful, but it spurs on improvement like nothing else.

You need a stubborn belief in an idea in order to see it realised.

If you really want to improve technology, if you want things to work better and be better, you've got to protect the person who spends a lot of effort, money, and time developing that new technology.

After the idea, there is plenty of time to learn the technology

Stumbling upon the next great invention in an 'ah-ha!' moment is a myth.
