It is hard to discuss about things that we can not imagine, but it is absolutely important to prepare your mind that lot of things are not gonna unfold on the way as we imagine it now. When this happens we push our limits. You might have to do things you never do, see things you can hardly believe.
We need to prepare ourselves that we will be confused because this is what happens when you cross limits and end up at place you never been before. We need to expect that. We need to be able to feel confident while being confused and in new situations.
Knowing what to do now and having done it already will give you an advantage later.
