"The only way to discover the limits of the possible is to go beyond them into the impossible."
Another thing I think should be avoided is extremely intense ideology because it cabbages up one's mind...when you're young it's easy to drift into royalties and when you announce that you're a loyal member...and you're gradually ruining your mind.

The key to success is to keep learning and adapting.
