Have you ever been all excited about a project? Have you envisioned it in your mind? Do you know exactly what you are going to do? Have you ever gone through that?
Have you ever actually started on the project and hate it midway? Maybe "hate" is too strong a word. Maybe it just didn't speak to you or it did not turn out anything like you thought and you did not like where it was going.
Yeah, that just happened with me.
