Every writer, every human being, has moments in their life they want to capture. This is my way of expressing my own moments. What I've come to discover through writing is that the only thing unique you can give to the world is your perspective. Yes, people have been in love, and yes people have lost loved ones, but those stories have already been written. Sorry, but you are too late. Now, there is a way you can avoid this. Write about you.
Write about the times where you felt the weirdest. Write about the times when you didn't fit in. Your emotions, your thoughts are only your own. No one in the world will ever think the exact way you do. Show them how you see the world. I can bet on my life that was exactly what the people who changed history did.
