Appearance: not a luxury, but a need!

Everybody is attracted to beautiful things. It is really a clever way to make people notice about your intelligence and intellect, without directly interrupting anything that person could be doing.

Of course, it doesn't give us assurance about people noticing or being interested in ourselves, but it is the most clever path.

Also, your appearance can change whatever thing people could think about you. People don't like to see ugly or unattractive people. So, you should improve the way you look, little by little, until you feel comfortable, and people around you don't avoid or run away from you. ;-)
