I was just watching a (the) video on A Bug Free Mind. And the thing that just struck me is that one of the main things related to achieving success is to have focus, to do one thing at the time, want one thing at the time, work on one thing at the time.

So I guess one of the Principles of Success is focus, which is not something different from the Principles of Success of Napoleon Hill, as his idea of definite purpose is also about focus.

And how it struck me was that Andy Shaw talks about the main thing Benjamin Franklin mentioned to be successful: focusing one one subject for one week (until you master it) AND THEN APPLY IT.

And that is also again exactly what Napoleon Hill teaches us: knowledge in itself is not useful, success is about APPLYING knowledge.
