The world matters. You matter. What you are doing is important. The life you live is important. What you believe in is important. Who you love, what you like. Who you are. Everything you have been through is important. Even if there is no sense to it. Its important.
Your friends matter, your hobbies. What you write here matters.
Because it is important to you, it is important to me. You matter to someone. Just know that.
