You've probably heard of 'The Secret' and The Law of Attraction.
Ideas like this are trying to explain natural phenomena that arise from humans interacting with the quantum.
They reach a large audience because they are simple and promise the masses big results with little effort.
We know we can't wish for something, and it will magically show up on our doorstep. We also know that if we work towards a goal, we can achieve it.
The magic comes from—and only comes from—combining strong mental visualization with strong action.
This means you can absolutely manifest your future... IF... you connect this mental energy to action.
You have to become a person that manifests consistently and then takes actions that lead to cause and effect results.
So yes, visualization and manifestation work, and the Law of Attraction is a Law... IF... they connect to action.
Let's expand 'The Secret' to this = DO THE WORK WHILE VISUALIZING YOUR FUTURE, AND YOU'LL GET AMAZING RESULTS IN LIFE.
This message wouldn't sell as many books because, like Jack Nicholson's character in A Few Good Men said, "YOU CAN'T HANDLE THE TRUTH."
All that said, the idea of visualizing and manifesting is paramount and should be a foundation you build on. Since you become what you think, what you think will dictate who you become, which will dictate your results
The key is to connect thinking to action. This creates a powerful feedback loop—better thinking leads to better actions, which leads to better results, which reinforces better thinking, and the cycle repeats.
This is why the growth-minded, optimistic, focused human that takes action is UNSTOPPABLE.
You can't hold him or her down. Period.
