A happy man is never ambitious. There is no need for him to be happy if he is ambitious, or if he is happy there is no need for him to be ambitious. Both things cannot exist together. If you are happy, ambition disappears; if you are ambitious you are miserable. Only in misery ambition grows. Ambition simply means you are not happy the way you are.
What dreams do you want to fulfill? That means the reality that you are living in is not giving you contentment, it is not enough; you want something more. Only a miserable mind wants something more. The very idea of the “more” is out of misery. But you seem to be very unconscious of your misery, or maybe very cunning. You don’t want to recognize it, you don’t want to confess it.
