One of the most important things in the world, especially today, is being yourself. Being yourself is one of the bravest and strongest thing you can do for yourself, it will give you so much joy in the life. Don't change because there are some people, who doesn't like the way you are.
Why try to be another person, than you are. What will it give you? Personally I have so much respect for the people, who doesn't give a damn about what other people think about them. Those people are the ones, I admire and look up to. Some people told me, that I am one of the persons who doesn't care about what other think, the fact is, I do care, sometimes I care too much, and I don't want to. I wanna be that girl who doesn't care about what other people think.
But just remember always be yourself, it the best you can do to yourself. And don't be the person other people think you should be, but the person YOU want to be.
