My personal beliefs ...

Do dreams really become true if we have the right mindset? Yes, or the dream changes into something better.

Don't you thing that there's a difference between what we want and what we are capable of? To quote some aphorism, "Inherent in the desire is the seeds of it's accomplishment." Capable is a long-time sequence word.

Are we capable of achieving all we want with the right mindset? Yes, but we do live in a physical universe so action and effort are important also.

Thanks for the rich questions.
