Take care of how you look. First impression on other people begins with how you look. Wear nice clothes, take care of your physical appearance beginning from your shoes till your hair. Do not make other people different in your eyes. All of us are humans in the end. Some of us have more money, some of us have darker skin, some of us have more IQ but in the end all of us humans. Tell yourself if someone can do I will do also if I have the same conditions which is my principal. It will remind you people are different but almost have same capabilities.

Rest is up to you.

Good luck.
