I'm not trying to be anyone's savior. I just try to think about the future and not be sad

It is important to view knowledge as sort of a semantic tree -- make sure you understand the fundamental principles, ie the trunk and big branches, before you get into the leaves/details or there is nothing for them to hang on to.

If you get up in the morning and think the future is going to be better, it is a bright day. Otherwise, it’s not.

Rockets are cool. There's no getting around that.

If you go back a few hundred years, what we take for granted today would seem like magic - being able to talk to people over long distances, to transmit images, flying, accessing vast amounts of data like an oracle. These are all things that would have been considered magic a few hundred years ago.
