I found am old interview where Tyler was asked something like how you dealt your dark times and he answered this question so wisely. He said that our generation deals with a lot of depression and a lot of s*ic*de and that those two topics are centered around the idea of purpose. Whats the purpose or whats the point of anything, and that sometimes it can cause us to lose our faith in ourselves. So he thought how he can create a purpose for himself that will help him carry on. So what he found out was that through art you can create a beginning of purpose ,not the whole purpose because its a big thing, but a begging of it. So when he was at his "dark hours", as he likes to call it, he thought if you have something that you've created and you are the only person that knows and can explain the meaning behind it, this might be the thing that will help you to get through those moments. For example he gave the song kitchen sink. No one really knows the meaning behind this song but him. And if he told us what this song means to him, then it kinda loses the meaning of purpose. Sorry for yapping but i really wanted to share this
