Very well formulated and insightful comment. Thanks for taking the time to write this. A lot of ambitious people seem to struggle with this question of external vs. internal motivation - although I think the most successful entrepeneurs don't, because for some of us this motivation is in fact internal. Some can actually say "do what you love/love what you do" and not lie through their teeth. And others are able to treat it in a purely businesslike manner, i.e. "this is a job and it's only temporary".

Many others, though, are as you say: Ambitious because external pressures have always told you it is a good idea, and because teachers, parents, professors and peers have always given you recognition for good work - it's a central part of your identity.
