Bill Gates - Co-Founder, Microsoft
Before becoming the richest person in the world, Bill Gates was a failed entrepreneur. Later on, he became the richest person in the world due to his hard work and his luxury home Xanadu 2.0 (The Bill Gates House), which is a computer controlled and accurate temperature control, music and lights are also noticeable.
Failure:
Initially, the company named Traff-O-Data was Bill Gates, which created reports of traffic counter and traffic engineers. Thus, the organization could help in the traffic. Originally named Traffic-Data-8008, this app could read traffic tape and process data. They started selling these products within the country but they failed, because the machine could not always work properly.
Then success
Paul Allen, associate with Bill Gates, said although Traffic-data did not work well, its experience helped him to build Microsoft in a few years.
In this way, Microsoft became the world's largest personal computer operator in a single day.
