Loneliness is the human condition. Cultivate it. The way it tunnels into you allows your soul room to grow. Never expect to outgrow loneliness. Never hope to find people who will understand you, someone to fill that space. An intelligent, sensitive person is the exception, the very great exception. If you expect to find people who will understand you, you will grow murderous with disappointment. The best you’ll ever do is to understand yourself, know what it is that you want, and not let the cattle stand in your way.

I have conflicting thoughts on the sentence "Never hope to find people who will understand you, someone to fill that space". Yes, it is very hard to find such person - someone who is in sync with you. Even good, close friends, don't necessarily understand you. They may just accept you. It's just that we can not afford to lose hope in finding that person. Hope can drive you crazy. But, in Andy Dufresne's words "Hope is a good thing, may be the best of things, no good thing ever dies".
I strongly agree with the last sentence "The best you’ll ever do is to understand yourself...". It echoes my views in the last para of this post.
