It means proud of who you are, even with the mistakes you made in the past. It means looking yourself in the mirror and thinking "This guy has his shit straight." While you reflect on your past life, you should smile and think "man I'm awesome." It means not using alcohol, drugs or violence to solve problems. To overcome and oppress those who bring you down. Whatever hurts you only makes you stronger. It's to think that you are a good person, but not to the point of arrogance or narcissism. You don't have to be the smartest kid in your class,you don't have to make a million dollars a year and you don't have to be popular to have self esteem and self respect.
I never done drugs, drank, got arrested and I have no record. Though I was not the most popular kid in school and I my grades aren't the greatest, I have to much self-respect to change who I am. I have a part time job at the city pound and I am currently in college working towards my degree.
