ambition comes from finding something you want to achieve. i would make a list of goals about where you want to be in 5 and 10 years. don't make them unattainable. Perhaps make some easier then others. Make some short term, and others long term. For me, I want to own a cottage, a house, have a couple children, become an experienced and respected teacher, travel each summer and have a great relationship with my wife (not married quite yet...that's a long term thing!). So, for me my ambition comes with achieving these goals.
