You just have to have an idea of what you want to happen and then find a way to narrow it down as you move closer and closer to your dream.
If you don't know what you really want, then you can't achieve it, can you? However, you can still start on your path before being 100% sure of what will happen. One way to be very specific about your dreams is to write them in your dream journal or in a notebook.
The first thing you need to do is to be specific about your dream so you can be on your way to making it happen.
