As you get older, you start to see that everything is the same and goes through cycles. The important stuff of my childhood (ex: having clothes that were sewhar fashionable), becomes irrelevant. Who cares if I'm wearing the same style of sandals for over 20 years now? You start to focus on what's more important to you. F** are reserved for important matters like arguing on HN about the superiority of Linux :).
When you see a child have a meltdown over not having their favorite bath towel available, you start to see how widening your scope means less care for minor problems. I have no time to worry about those things as I have bigger problems (working on marriage, work due dates, educating my kid...etc). It makes one wonder how chill an immortal being would be after milennia.
