Does really matter about how you look like?

Yes, it does to some extent. People judge others by how they look ( this is not right, but it is what happens) and it only takes a few seconds for this to happen. Once this takes place that judgment rules how the person responds to the other person. So, if you look like a slob or not really good this is how the other person will see you and respond. This can be wrong but it takes place. If you are applying for a job or going to a new place this can determine if you get the job or make new friends. You need an awareness of how you look to others if you wish to be successful.
