First and foremost, be who you are. You will meet people who tell you that you must act a certain way or be a certain thing. Don’t put too much stock into what comes from people you don’t want to emulate. Remember that your family will always be there for you, even when your friends are not.
You will find many different interests and hobbies throughout the next few years. You will even find a bit of success in some areas of your life. It will be easy to compare yourself to others and to determine your own success based on what others say. If you are proud of something that you have accomplished, be proud of it regardless of what anyone else says or does. Those who tear you down are not worth your time. Find people who will support and encourage you in your endeavors. This will benefit you more than you know.
Lastly, be kind to others even when they are unkind to you. When someone says something mean or rude to you just brush it off, don’t give them the satisfaction of letting them know that they got under your skin. Simply pay the insult or offence no attention and continue on with your life. By doing this, you will take away any power that others think they have over you and you will be able to live a much happier life. When you know there is a repeat offender, distance yourself from them. There is no point in setting yourself up to have to endure the length of unnecessary and unpleasant interaction. But above all, be yourself.
