Choose your counsel, company and companions wisely: beware seeking wise words of advice from a fool or expecting informed opinions or decisions from the ignorant.
One can always satisfy oneself, I suppose; it's other people one can't satisfy. One thinks one's way of life is sound and then comes an external vision to say: you are a fake, you are nothing, you're animal and must die, and no one will know you were ever here. It's an intimation of the whole absurdity of what you are and do. It's the worst kind of despair.
Do not let other people invade your personality. Remember that every human being is a unique phenomenon, and worth developing. You will meet many who have no resources of their own, and who will try to fasten themselves upon you. You will find others eager to tell you what to do and think and be. But it is better to go apart and learn to be yourself.
