I suspect that one important part is to get rid of other people's ideas. For example, in this discussion, currently the most upvoted answer says that your purpose must be a source of income. Well, not really. Some people have a day job to keep their bills, and write poetry at night, and they consider the poetry to be their purpose. Of course, it is awesome if your purpose can also become a source of income (because then you can spend more time doing it), but do not put the cart before the horse. First find out what your purpose is, only then start thinking about making money from it. Similarly, "what you are good at doing" is a nice thing, but that often comes with practice. Do not give up on trying new things. Try different things. Afterwards, notice the emotions connected with your memories of doing those things. Explore around the things that felt good; try doing something similar but different.
