That is repeated so often that it has stopped carrying information.
The useful question is which five years and why.
Very few firms fail because the idea was wrong.
Most fail because they while the idea was still being tested.
, not vision, decides how many attempts a gets.
This is why the same idea succeeds in one city and folds in another.
Where is patient, the second attempt happens.
Where it is not, the returns to work.
Survivor stories all of this by construction.
They are told by the people whose cash lasted.
Reading only those accounts teaches confidence rather than judgement.
