I really believe people use diversification the wrong way in this business. They think they are protecting themselves by working multiple markets. They are actually hurting their growth because they can't leverage their expertise, product creation, customers, and time to grow faster by concentrating on one big market. In big markets, there is no need for protection because thousands to millions of people are entering the market daily. You only have so much time in the day so it is better to work a market until you can't squeeze anymore money out of it before moving on. Once you build up your cashcow, invest it in something else that doesn't require a lot of time.
