Movie and TV wisdom (serious) [spoilers]

Looking for little bits of wisdom people have gleamed from movies and tv. Doesn’t have to be the moral of the whole story, it could be a single scene, or a character development - but it should have been helpful or relevant to you personally. There’s already been a humorous thread on the same topic, so I’d like to keep this limited to actually helpful or insightful things. Feel free to spoil.

My example - the Christian Slater’s renegade DJ movie - he inadvertently encourages a kid to commit suicide. When he finds out what happens he tells kids that are depressed to not give up but instead to act out. What I got out of this was the idea that if it seems like there’s nothing to live for, there’s a brights side - this means there’s also nothing to lose. If you are really down and out, it’s a great time to task risks and do the things you were always afraid to do.

Balki to Cousin Larry: “On Mypos, if we can’t make friends with a skunk, we consider that a good thing.”

Captain Picard: “The man who’s convinced himself he’s going to die tomorrow usually finds a way to make it happen.”

True enough.

From the 1970s TV show Kung Fu, during a martial arts lesson:

“Avoid rather than check, check rather than hurt, hurt rather than maim, maim rather than kill; for all life is precious, nor can any be replaced.”
