I met with the owner of TAFT Clothing today for lunch. If you haven't heard of them, you should check them out, they're a great company.
Without going into too much detail, he (the owner) has been able to build a multi-million dollar business purely through his own intuition and the power of the internet. Even today, he runs the business primarily out of his house with his wife. To the outside eye, someone may assume that TAFT has 100's of employees, but in reality, it's just a small, driven team.
It's companies like this that inspire me to be able to accomplish great things in my own company and life. The internet has provided endless opportunity for great things to happen. I'm sure business 50 years ago was much different than it is today. Today, with the right product, business strategy and work ethic, a business can get really big, really fast.
