Once upon a time three Seekers came to an old Zen master.
"Master", they asked "what do you do to be happy and content? We’d wish to be as happy as you."
The old one responded with a mild smile: “When I lie down, I lie down. When I get up, I get up. When I go, I go and when I eat, I eat.”
The seekers looked at each other in confusion. One of them bursted out, asking: “Please, don’t make fun of us. The things you say, we do them, too. We sleep, eat and go. But we’re not happy. So what is your secret?”
The old Zen master felt the resentment and agitation of the seekers and spoke: “Of course you, too, lie down and you, too, go and eat. But while you’re lying down, you already think about getting up. While you’re getting up, you already think about where you might go to and while you’re going, you already ask yourself what you might eat later. So your thoughts are constantly somewhere else, from where you are. Actual Life happens in the intersection between past and future. Just go with this one immeasurable moment, and you might have the chance to be truly happy!”

I hope this text is as helpful to anyone else as it was (and still is) for me! :D
