An abundance mindset is a practice. The key is releasing your limiting beliefs and recognize that we are not our mind, our mind is a holding tank of files that we have accumulated since the age of 3. Most of what we heard, saw and absorbed are beliefs. But those beliefs are not your beliefs. They are beliefs you absorbed that are the beliefs of others.

Most if not all of scarcity thinking is learned from the behaviors and thoughts you have been influenced by from family, friends, school etc.
