This wasn't very clear for me at the beginning when I heard a few people with a net worth of over $100m telling their audiences that if they wanted to become like them, they should develop a big ego. But now I second that advice.
However, a distinction needs to be made between the two types of this term:
One is commonly what Eckhart Tolle describes as your attachment to your false self, façade or similar attributes and labels, ignoring the larger persona we embody.
The other one is a larger-than-life persona we could become.
So everyone who tells you to grow a big ego refers to the latter one. This means that if you intend to manifest owning private planes and yachts, you can’t be an NPC.
Another insight that supports this view I got from the book The Trap by David Icke, who has been researching the nature of our reality for decades, is that to alter your reality, you need to alter the ‘perceiver’ (who you see yourself as). I don’t need to mention that the political systems and the media work tirelessly towards suppressing that part of you so you can be easily managed. Hence, it is your birthright to rebel.
So let’s imagine this scenario. Mark, an average guy, tries to manifest one billion dollars.
Here is what his subconscious mind will typically say:
Motivation? Unfortunately, he is motivated only by the downside (avoiding pain). He has no upside motivation. That's not good.
Is he happy with living in the same house? Maybe he needs an upgrade? Yes, he is very content there.
Would he like to be a part of some club for extremely successful? It appears not; the company of his drinking buddies is enough for him.
Will he be ok with being sued and needing to sue someone sometimes? That’s unavoidable on the way to becoming a billionaire. No, he does not want any legal problems.
Does he want to build a dynasty? No.
Diagnosis: Mark needs to desire larger-than-life things for his intention to manifest. But before he makes that happen, he needs to gain the necessary insights (to alter the ‘perceiver’). This typically boils down to exploring subjects such as fulfilling his human potential, the mechanics of power,
the money game, or giving back to the community. He needs to do so to find a use for the amount of money he has asked for. This kind of egocentric approach has another benefit: If Mark acts as if he always wins, he will eventually succeed. If you imitate a character role, you will soon become that person. And the mere acting like I am attracts those who recognize you as if you were the real deal.
Paradoxically, it is the first type of 'ego' that prevents people from transforming into the second. People typically say ‘I know’ when in reality they have no clue what to do. Some stick to labels such as ‘I’m a lighworker’ and they defy any beliefs that could harm that identity. That’s why a larger-than-life persona is frowned upon.
