I have dropped Hero because I no longer do martial arts, Hero is still an amazing subliminal that will help you improve rapidly in any skill especially if it’s physical, it’s also a good subliminal to develop virtues, a sense of invincibility and courage and a fearsome and respectable aura.
If your goal is wealth I would do other subliminals, but you can add it to your stack if you jiu jitsu, rock climbing and guitar are important enough for you, you can have one or two wealth subs and Hero, why not?
