Star Trek Enterprise Theme Song - Faith of the Heart

Love the lyrics

Lesson: Have Faith and the River Will Provide

Faith, Treachery and the Great River made me a believer.
Since then I've faith in the Great Material Continuum, you know, the force that binds the universe together.

Remember - there are millions upon millions of worlds in the universe, each one filled with too much of one thing and not enough of another. And the Great Continuum flows through them all, like a mighty river, from 'have' to 'want' and back again. And if we navigate the Continuum with skill and grace, our ship will be filled with everything our hearts desire

Lesson: Try Optimism

Borg Optimism [VOY Episode 5x01]

Seven of Nine: Chance is irrelevant. We will succeed.
The Doctor: A vote of Borg confidence. Who could argue with that?

Lesson: Keep on Trying. Never Give Up!

[DS9 - Episode 6x04]

Captain Sisko: Take a good look at this, people. It says something about this ship. It says that we will fight, and we will keep on fighting, until we can't fight any more!

Yes, sir!

Movie: First Contact

When Picard and Lily Sloane are on the Enterprise and talking about destroying the Borg and in the end the Captain is quoting from "Moby Dick".

Captain Jean-Luc Picard: "And he piled upon the whale's white hump, the sum of all the rage and hate felt by his whole race. If his chest had been a cannon, he would have shot his heart upon it."

Movie: Generations

The very end of the movie. Picard & Riker in the destroyed Enterprise.

Captain Jean-Luc Picard: "Someone once told me that time was a predator that stalked us all our lives. I rather believe that time is a companion who goes with us on the journey and reminds us to cherish every moment, because it will never come again. What we leave behind is not as important as how we've lived. After all Number One, we're only mortal."
Commander William T. Riker: "Speak for yourself sir, I plan to live forever."
