I have a riddle for you.

When can you divide 100 by 5 and end up with a result that adds up to less than 100?

The answer, when you divide your attention.

In the past few years I’ve seen web entrepreneurs of two categories. The first is the category of people doing lots of different loosely or unrelated projects. The second is people who do different things, but when they are different, they are related. Project A compounds the value of project B.

Take a guess which category is full of people running successful multi-million dollar companies today.
