Remember why you pursue these goals. Remember the real and deep reasons why you decided this was what you wanted to do. Write them doen if you need it. Hang them on the wall if you need it.Do it, get experience in it. I don't know what your goals are but let's say you want to write a book: get working. Read, make research, write down your ideas, make a draft.It's ok to think about the future you, actually, if you want to achieve great things, you have to think a bit before acting. However, that should not keep you from living in the moment. If you keep planning what your life should be but never start acting so it becomes the way you want it, it's never gonna happen.
