[Harty Potter] Does Felix Felicitus bend reality to the user’s advantage, or does it just make them more aware of the opportunities around them?

*Felix Felicis

It doesn't bend reality, it just mentally guides them towards the best *possible* outcome in seeking their goals. That's why Harry got the memory from Slughorn *and* managed to break up Ginny and Dean, because he openly wanted the first and subconsciously wanted the second. 

It has limits, though. That's why Harry didn't use it to break into the Room of Requirement. Luck alone couldn't let him overcome a powerful spell.
