You said you needed a dollar.

There is a moment in life when you find yourself living based on memories, trying to stick to them, to the past, because that is what you know, what you are used to.
Being used to something, someone, is easy, my friend. You need courage to move on, to leave behind you what you know and what is not good (enough) for you. It takes time, strength and courage.
It is easy to tell, though. You will not believe how many times I have tried to move on, to get over things, people, thoughts. It is just not easy, but when these memories become hurtful, you need to chose between living on your own or dying with your memories.
That's it.
