Anything is possible. But if you are trying to get rich without anyone knowing about it, you will be holding yourself back from doing what you ought. Let me introduce you to a line of thought that can free your mind.
Getting rich always involve serving. You would need to serve a category of people and help them get a particular result. All you have to do is to forget about yourself. Forget about yourself and just focus on those getting the result they want from your service. That way, you will not be bothered by those looking at you for the money you have.
You are too conscious of yourself. That is what is holding you back. Become concerned about others that you ignore the concerns for yourself. If you make a lot of money by genuinely serving people, you’ll be alright. You just have to make that mental transition first.
