What is good? What is beautiful? What is the standard of everything? People are always judging others. 'You are too thin, you're too fat, you are not good or you are ugly.'
I see people define good as what most people like. You can see people asking the waiters what are the most popular dishes at a restaurant. They think what others like are what they like. But this is not true, everybody likes different things.
So this lets us know that don't judge things or people, believe that there are always people that are "better" than us, which I mean we are all different.
A little girl used to teach me how to read a staff. To be completely honest, I was annoyed, but I didn't want to let her down so I, however, listened carefully.
I also heard a person teaching me how to fry fries today. He said that the advance way is frying it without peeling. Since when we have to define food is advance or not? The reason I love having well-peeled fries is not because how other people define it, it's only because I define it as delicious food.
Accordingly, don't go to a restaurant only for the reasons that it's expensive and "advance". If you think this is the only way to brag, to show your wealth or to have somebody's attention, then you really should go back to school. You can impress people by your, for instance, amazing piano skills or fascinating speaking ability. Always remember that the more knowledge we know, the more omnipotent we are. It's never too much to learn.
