On the whole, the practice of meditation is a sloppy job. You have to accept that you have been a fool and start with being foolish. In the beginning, deciding to try the practice of meditation is just leaping to some conclusion about what to do. In doing the practice at the beginning, rather than really meditating, you just imagine that you are meditating. So to begin with, the whole practice is based on confusion. And confusion is accepted as part of the path. Since the situation is very loose and unorganized, it is as though you are leaping into unknown territory. A lot of people find that very frightening. You are not quite sure what you are involved with. But that is the only way to get into the practice.
