"Fact" could be explained in "something which most people believe", and "fiction" is something opposite. When a fiction is being repeat, repeat and repeat, it'll slowly becoming fact.
wiwt would give this example: DRAGON.


At the end, you can see a lot of artifact potrait dragon, buildings, scruptures, 3D toys, and so on.
Now, dragon should be fact or fiction?
Another example, you've been told that you don't look healthy today, in a row, by 3 friends of yours, you would propably ring your doctor for appointment.
In this case, "you don't look healthy today" should be fact or fiction?
Applying the same rule, "you can't make it", "you are looser", "you are poor", "you are lazy", "you are hopeless", "you are bla-bla-bla", all sort of damn you receive everyday, from your friend or even you yourself, would probably come true.
wiwt suggest, keep saying "you are smart", "you are great", "you are healthy", "you are rich and wealthy", "you are evergetic", "you are superb", to your friend and yourself. You can feel the changes from "fiction" to "fact".
Fact or fiction doesn't metter, the effect and impact does!
