At some point you just have to start.

I knew at some point I would have to grow up. I had followed her, listened to her and copied her all my life. She was infuriating, but inspiring and I loved her very much. But and I am not sure exactly when, I realised that I was not ‘just’ her little sister. I was me. I was my own person and I could be what I wanted. I could be different from how I thought I should be. So I leapt out of her shadow, the little sister no longer.
