Thresholds

It’s incorrect to say that ‘salt is bad for you’.

A certain level of salt (sodium chloride) is critical for good health. Certainly too much is dangerous.

It’s incorrect to say that ‘being efficent’ will help your success. Too much efficiency (getting stuff done) can damage your effectiveness (getting the correct things done).

There is a threshold for everything: salt, sunlight, exercise…….being smart is reaching the threshold and no more.

Productivity

is not getting stuff done. It is getting the right stuff done. and the more you know what is the right stuff the easier it is to be productive.

Start with that question: what really needs to be done and why?
