There is no such thing as useless knowledge. I have endless examples proving that every opportunity to learn something new should be used.
Yesterday, for instance, I spent all day shopping, running errands, going from one place to another. It was extremely hot, my belly was flapping around, and I was exhausted.
When I finally got home, I discovered that a new book had arrived. I wasn’t sure I had energy or time to start a new book then and there.
I got over myself, though, and started the new book. My reward caught up with me on page 46 where I discovered a fact that allowed me to avoid a very embarrassing mistake in an article I was going to submit today. If I had postponed the book by a single day, I would have sent out an article with a mistake.
Given that I only have this career because 14,5 years ago I memorized some completely random words in Spanish in preparation for a placement test I had no chance of passing, I now know for sure that there is no useless knowledge.
