What are three major turning points of Napoleon Bonaparte's life?

There are many different approaches one can take in
answering this question.  One particular avenue is to discuss the role the French
Revolution had on him.  The Revolution's course of action made Napoleon its conclusion. 
The ability to seize power in a setting where there was no construction of it could be
one turning point in his life where his political legacy was made into what it was. 
Regardless of if one sees him as an individual who surreptitiously gained power or one
who was the logical extension of the Revolution, this moment in time was a significant
moment in Bonaparte's life.  Another turning point in Napoleon's life had to be the
frustrations he experienced with trying to defeat England.  It seemed as if the presence
of the British in the face of Napoleon's desire to eliminate them helped to bring a
sense of imperfection to him and allowed a sense of thwarted desire to become evident, a
theme that come to define Napoleon's reign.  Naturally, the failure at Waterloo has
become regarded as proverbial, demonstrating a significant turning point in his
life.
