Reasons Why Quantum Mechanics is Not that Hard
Common sense deceives you of understanding Quantum mechanics; You need to make your mind flow. Let's just say that your mind will flow on water with no penetration of common sense of denying the concept of QM of how can such a concept be even possible. You have to use advanced critical thinking for this. When I first see QM, I just don't care about if it lacks proportion of common sense, it just makes sense to me maybe because I have a very distinctive mindset. I just know that it's possible.
Developed by the own Eccentric Quantum physicist under the name of Richard Feynman A.K.A the great explainer. No, I have not used the Feynman method to grasp QM, I put my reasoning on item #1. I heard that this method will make you learn anything, especially Complex subjects like Algebra, Calculus, Quantum physics, Relativity, etc. If the method doesn't work then I suggest try something else.
During my first month on 8th grade, we have to learn about subatomic particles of how they work and the atoms. To be honest what they teach me is way too basic the concepts of Quantum physics that I taught myself, it is not even at my studies at all. Anyway I suggest starting with Bohr's model of the atom, or Planck's emission and absorption of the atom, or whatever...
The majority of how I understand Quantum mechanics is this app. It's more resourceful, detailed, helpful and fun for my studies. The rest other than the majority is books, YouTube, and taking notes.
I made a list about it.
Richard Feynman is the great explainer and he will help you grasp Quantum physics, or somebody

I've been through so many rabbit holes that I believe I more than know & understand what life is, our subconsciousness/consciousness goes beyond the laws of quantum physics/mechanics, after we die we can travel between universes, universes have its own shape that has no restrictions nor limitations
