Mastery or mediocracy

Tempting as it may be, you can't be the best in the world at solving multiple problems for multiple customer types. 

But, you can be the best in the world at solving one problem for one customer segment.

Being good enough doesn't cut it any more.  

Aim to be the best in the world or nothing at all. 

Questions to ponder:

• Am I aiming to be the best in the world for one customer segment or good enough across several customer segments?
• What are the implicit and explicit costs and trade-offs of doing it this way?
