One sees the world according to one's vision. But one's vision can be quite small; you measure things according to your own small measurement, after all.

Though you may not know how to save anyone now, it doesn't mean you won't be able to later on, if you try. Humans are amazing like that. They are able to take a small sound like a rain drop and create music out of it. They are able to look at a white canvas and imagine a whole world for it. But a painter isn't born knowing they can pain just like a musician isn't born knowing they can create music.

That's why everything is important, even if it goes by unnoticed. Everything forms you, in a way, for you are made of your own mind and things around you. This place does too. Its shops. Its people. Its rain. They are part of you and they help you form "you", shape "you" and above all, allow you to understand yourself better.

That's why those you have met and this place are important. You should cherish it.
