Who cares if something is ultimately right or wrong. Who cares if it is true or not. Believing and doing what serves you will always be better in the long run.
For example, is it true that making money is hard? I don’t care. But if I believe that making money is hard it sure will be for me. Vs. if I believe that making money is easy, even if it isn’t, I will have a better chance of making money being easy for me.
Is it easy to lose weight? Who cares. If you believe it is hard it will be. But if you believe it is easy, it greatly increases your chances of it being so.
So instead focus on if the belief, thought and/or action serves you and the people around you. Not if it is right or wrong, true or false. Remember, you create your reality by what you focus on.
