Be yourself - this phrase you have heard too many times and read quotes related to it countless times over. But still, we all need to be reminded sometimes to be just that, to let ourselves reminded what we're made of.
Follow your inner moonlight; don't hide the madness.
Embrace yourself. That's first and foremost. We all idolize some people, we wish to be like them but we forget that we're not them. You are who you are and they are who they are. Neither you can be them nor anyone else going to make you feel like you're like the person you idolize. So, don't try to imitate someone else. Be who you are.
Be proud. More importantly, be proud of who you are. Yes, be proud of yourself. The real you, the "you" you, the one with all the flaws and perfection, be proud of that person. If only you're proud of yourself then only can you make others proud of you.
Love yourself. There are bigger love than self-love, but love starts within yourself. To love one own self is the hardest thing to do because it requires that you love every bit of yourself, every bit that is good and bad. Tell yourself that you love the person you're every day. Self-love is important to grow confidence. It will bring out the courage from inside.
Be brave. Be bold. Speak out what's on your mind and not what other people want to hear from you. Don't try to sound like someone else. Bring out your own voice and show everyone who you are. Don't let anyone make you doubt yourself. If you know in your heart then don't shy away.
Imperfection is beauty, madness is genius and it's better to be absolutely ridiculous than absolutely boring. - Marilyn Monroe
