I'm going to leave open my book with an extra difficult-to-understand-looking page to hopefully impress someone when I go to the toilet at university
Why do you think you need to do such a thing to impress others?
I really like the person that I'm trying to impress.
I want to impress someone that I like as well, and I feel like it's a clever thing what you're trying to do, but I feel like you're going to start your relationship with this person on a lie. You should not lie by putting difficult to understand scribbles on your book just to impress someone, but you should impress people about the things that you are really good at so that when they get to know you, they would fall in love with the person that's real and authentic.
I know but this feels easier and better
Just because something is easier doesn't mean its right. What would happen if the person asks you about the subject matter in the book? They would know you're a fraud.
