It makes you narrow minded
I wrote two conflicting posts. One claimed that concentration is the new competitive advantage and the other stated that focus is foolish....
... both make decent arguments. The problem is that they are both half-truths. They are both ideas that are true under some but not all conditions.
Is focus important? Sometimes. Maybe. It depends. You will never get anywhere if don't focus at some point, but if focus causes you to have tunnel vision then it will be your downfall.
