Life has given us a great and infinitely noble gift, that is, youth: full of strength, expectation, ambition of seeking knowledge and struggle, hope, confidence and youth. Ostrovsky

Ambition is just a slave to memory. It was born vigorously, but it was difficult to grow. -Shakespeare

Worst of all, people's lives are often hindered by wrong ambitions without knowing it. Only when they get rid of those obstacles can they understand it. -Goethe
