You are beautiful. You are good enough for yourself. Be comfortable with yourself. Be okay with your low IQ. Be comfortable with what you have done for yourself. Let other people do their own things.
Do not compare yourself to other people. Because you are running your own race. Because you have a different target. Because you are not going to where they are going. Because they do not know your dreams. Because you are you, not them.
Do not forget who you are. Remember that the only relationship that matters is the one you have with yourself. Because if you are not in a relationship with yourself, then it means you are in a relationship with another person. It means you are loving another person more than yourself. It means you are allowing other people to tell you how to run your affairs. It means you are just existing, not really living.
Remember that you are here to live, not to exist. So to live your life, to do your own things, you must take your life back. You must do your own things. You must live your life on your own terms. Are you willing to do that for yourself?
