I want Affirmations and Visualization

Hi Everyone,
I hope someone out there has the answers I need about Affirmations and Visualization. I am being told the reason my wishes don’t become reality, manifest is because I am not doing this correctly.
What is the “Proper” way or “Certain way” to word affirmations to get them into the subconscious so they resonate with what I am trying to manifest?
AND!
Is there a proper way to visualize what I want to make it more than a dream?
Any answers would be most appreciated!
Love and Peace,
