As citizens of Earth, our responsibility is to retain the stability of the system or to positively grow the system. Ambitions are often completely in the way of that. Many ambitious projects resulted in colossal damage to the environment or other people. I do not believe that "citizens of Earth" and "huge ambitions" really even belong in the same sentence, as a person with huge ambitions is focused on the short-term progress of the individual, and not the Earth they are a citizen of. Being happy from fulfilling your dreams only works if your dreams are fulfillable. If they're not, you might very well end up rather unhappy. Happiness in this sense often comes down to a balance between legitimately required things, and managing expectations. Ambition, or large dreams, hardly seem required for happiness, and I'm inclined to say are actually detrimental to it. Happiness and success should really be kept separate, and both be ends to themselves. A given person deserves their happiness, and useful projects should be completed because they're useful. Deriving happiness from completing a project means you have now made the project all about you, and from here comes corruption, such as continuing a project that has lost its usefulness, taking advantage of other people, or manipulating p-values.
