Walking helps me a lot to feel alive, and I do this every single day, my wife and I. We have long conversations about nature, and we also walk silently, just contemplating.
By sharing something, I realized that I'm not alone, that there are a lot of people that share with me the same preoccupations, the same ideas, the same ideals, and the same quest for a meaning for this life.
Forget everything you've ever learned about the stars and they'll once more be transformed into angels, or into children, or into whatever you want to believe at that moment. It won't make you more stupid - after all, it's only a game - but it could enrich your life.
We suffer because we feel we are giving more than we receive. We suffer because our love is going unrecognized. We suffer because we are unable to impose our own rules.
In real life, love has to be possible. Even if it is not returned right away, love can only survive when the hope exists that you will be able to win over the person you desire.
Don't be like those people who believe in "positive thinking" and tell themselves that they're loved and strong and capable. You don't need to do that because you know it already.
