In the French and Indian war, what actions did William Pitt take to turn the tide of the war?

The French and Indian War was not going well for the
British prior to William Pitt.  There were severe losses being endured by the English. 
Most notably, the loss suffered by well respected British General Edward Braddock helped
to enhance the perception that the French were going to win.  Pitt saw the war as an
opportunity for British muscle to be flexed, and an opportunity for the British to
become a world power.  Pitt sought out and sent the best British Generals to send to the
new world in order to commandeer the English forces to victory.  Pitt's belief that the
war was winnable and a moment for the British to seize helped to inspire a wave of
patriotism, largely credited to Pitt's leadership.  Pitt was able to secure the use of
the navy, a technique that would spell out British dominance for quite some time.  In
the end, Pitt's leadership and commitment to British victory resulted in the repelling
and expelling of the French and leading to the British presence in North America as
uncontested.
