If you don't know what you want, everything that you get is "IT".
At one point you might decide that what you get is not what you want. At one point you might decide to look for what you want.
Start with simple things. I want to eat. What do I want to eat?
I want to write? What about?
I don't want to sing. Moving on. Keep a diary. We do know what we want, but sometimes the knowledge is clouded.
