Yes, people do judge you by your appearance and the fact is that good looking people do have a decided advantage over their simpler bretherns, whether it comes to their relationships or their career.
The fact of the matter is that good looks do count.
This is because we as a society are obssessed with looks. We think that attractive people are better people. So we are ready to give them that extra chance. Good looking people are thought to be more confident than plainer people and so get breakthroughs easily.
However, it is important to remember that looks will just give you that initial break and that they are not enough. Even good looking people need to be good at what they are doing in order to be successful.
Hence folks, Beauty counts but so does Brains.
