The self-help gurus are also right.
The way to get things done effectively is to believe that you can.
Unbreakable faith is the fastest route to progress that exists.
It just comes with the dangers of ignorance.
If you put your faith in the wrong thing, then you will fail big. If you put your faith in the right thing, then you move faster than everyone.
So the best answer I know is to train your ability to believe and your belief. Practice believing in something small and go do it. And if you’re wrong, it’s fine.
And if you’re right, then you’ve increased your capacity to believe. Do this over an extended period of time, and you will become an unstoppable force because you will have belief in your ability to achieve backed by competence.
