Something I've seen a lot of recently is people knocking people down. So what if you are dreaming big!?
Your dreams are your dreams and that's what makes you, don't ever let it break you. Don't let people tell you that you cant do something that you Know you can do. Because You know Yourself better than anyone does.
And if anyone ever tries to tell you, that you can't do what You know you can and want to do, let it drive you and inspire you to meet and beat that dream. Because it can be done. And only you can make it so.
