Illusions can be fun, but also dangerous. Today I went to the museum of illusions. When you have illusions about your career, this is dangerous. Staying in the same place, without any chance of progress, is usually bad (not always).
But when you go to a show, or museum, illusions can be very entertaining.
It is also hard to change other people’s illusions. So be careful what illusions you are creating and what illusions you believe in. Because they might cost you a lot.
