Daydreaming, as comforting as it can be, can also be quite toxic to progress if you let it. A lot of times daydreams are something we separate from reality, meaning the two do not overlap. This is fine when you are dreaming about dragons, or winning the super bowl with a hail mary pass as time runs out - those things aren't going to happen (sorry!). But when we live out plausible scenarios out in our head and group them in with the dragons and wizards, there's a problem. It's like telling ourselves when thinking it "but that will never happen." It depends on the person, but it may be giving a really good speech, or going on a date with a movie kiss at the end, or simply being really comfortable in conversation. Yes, it's true that things don't go exactly as planned in our heads, but that doesn't make them fictional, unattainable things.
This is just something I noticed. For the longest time I think I had this problem, where I would live my life in my head and the idea of anything I conjuring up being real never even crossed my mind as possible. (noting the difference between daydreams and going through a situation in my head as it would "really happen"). Then last summer, the strangest thing happened and things I dreamed about actually happened in my reality. Maybe not exactly, but pretty close. So when I'm daydreaming, I sometimes have to remind myself, if I really wanted to I could make that stuff happen. It's more than just a fantasy, it can be plans for the future.
