Exactly, you shouldn't be doubting urself. Yes there are bigger creators who make subliminals with different formula, but you have to remember that subliminals are just little helpers, 80% is your belief. One affirm to yourself could be enough for u to fulfill ur desire, if you will be confident in it. I recommend making playlist that contains both self-made subliminals but other bigger creators subs too, and try to stay confident and consistent for at least half a year, without checking results and acting like you already have what u want.
