If you're also desperately seeking an easier way to be successful, then boy, do I have good news for you.
Tom Holland, the GOAT of Spider-Men, is living proof that manifesting your dreams into reality can sometimes actually work.
Let's start with Spider-Man. In a 2013 red carpet interview, Tom said he'd like to see himself star in something "less serious" than The Impossible (2012).
He then added that if he were to play a superhero, it would be Spider-Man, and that maybe in "10 years time" he could see himself in the role. Four years later, in 2016, Tom landed the role of Spider-Man in Captain America: Civil War.
He then manifested the next part of his career (in what appears to be a livestream) into starring in a movie adaptation of his favorite video game: Uncharted.
And finally, last but probably the most magical of all, was his manifestation into winning the girl of his dreams (Zendaya).
