Stop being unhappy with yourself. You are perfect.
Stop wishing you liked someone else, or wishing people liked you as much as they like someone else.
Stop trying to get attention from those who hurt you.
Stop hating your body, your face, your personality, your quirks.
Love them. Without those things you wouldn't be you.
And, why would you want to be anyone else?
Be confident with who you are.
Smile. It'll draw people in.
If anyone hates on you because you are happy with yourself, then you stick your middle finger in the air, and say screw it!
Your happiness will not be depended on anyone anymore.
Life is too short to be perfect.
Love your imperfections, they make you, you.
And, your flaws is what make you beautiful. So, be you. Because, you, are pretty amazing!
Can you remember the last time you were in love? Your heart went ahhh. It is such a wonderful feeling. It's the same thing with loving yourself except that you will never leave. Once you have love for yourself, it's with you for the rest of your life, so you want to make it the best relationship you can have.
Stop hating yourself for everything you aren't. Start loving yourself for everything that you are.
Spend a little more time trying to make something of yourself and a little less time trying to impress people.
