Human nature is to resist change, generally based in fear or lack of understanding. The problem is, in business and in nature, you grow or you go. Every product, every company, has a life cycle.
The reason some people succeed beyond anyone's expectations is, they think differently and act differently. Most of the time this results in failure, but sometimes you just might change the world.
Look at Apple. The little company in Cupertino brought the Silicon Valley (and then beyond) the Apple II. By the 90's, common thought was their use and time had passed; the PC based architecture was fueling business and business had the money to buy computers. Desktops were in accountnt's cubes first then they were everywhere. The Macintosh was used for documentation, running Word. Then Windows and MS Office took over. Engineers were running massive hardware and CAD software. Apple was done.
This past week Apple became the 1st $1T company.
Let the naysayers naysay. In Silicon Valley we take risk and embrace change. The results speak for themselves.
