Why don’t you believe that manifesting is easy? This usually boils down to your life experience, the values instilled in you throughout your upbringing and the limiting beliefs created in your life.
After a certain point, the beliefs you picked up during childhood must be kept or discarded in accordance to who you are now because you are an adult choosing your own beliefs. The adult you aim to become stands their ground and creates their life and happiness. This adult puts their own opinion above the opinions of others.
The adult you aim to be knows that making a choice just to please someone else would still mean making a choice that hurts their own happiness…and they refuse to do it.
