Do you really want to write a book? Or do you actually want to dream about writing a book?
Do you really want to drop everything and move to a sea-side town? Or do you want to dream about dropping everything and move to a sea-side town?
Both are fine. Both can be fulfilling, because often, having a dream is enough.
But both are not the same.
Only you will know if it’s the dream that makes you happy, or the action you want to take.
