To be creative means to be in love with life. You can be creative only if you love life enough that you want to enhance its beauty, you want to bring a little more music to it, a little more poetry to it, a little more dance to it.
Be gentle. Fill yourself up with love instead of hate. Fill yourself up with art, books, knowledge, experiences. Surround yourself with people who have nothing but love to give. These things are important. They will help you learn how to love.
