I've found it all really depends on the person. Some people put a lot of pressure on themselves, and others don't have a care in the world.
Popularity is a huge thing among a lot of my friends. My one friend wouldn't even go out because the back of his neck was 2 days grown. Everyone thinks they have to look perfect, but not me I wear whatever I get by.
Yes, popularity creates huge pressure on human mind. In such a situation one should not lost himself or herself. The person must remember his/her sanctity of individual existence which is superior of any emotional entity.
