Train your fish

There’s nothing inherently wrong with a training kit for fish. It’s just the loss of possibility in your life. If you sit down in front of your fish tank and spend hours training your fish to swim through hoops and bump an underwater ball into an underwater soccer goal, you are implicitly saying, “I am not capable of more than this. I hereby decline my life’s utility.”

When your friends come over and you show them your trained fish, they will congratulate you. But not for training the fish. They are congratulating you for learning about yourself something that I (and many others) have learned ourselves: we will never do anything important in our lives, we will never move humanity forward as a species or culture, so it’s best if we just stay out of the way of the people who are.
