Paradigms are about beliefs. Believes that rule your daily life.
And paradigms are putting a limit you place on yourself. What is really important is to find out why you do it, what is the reasoning that supports your limiting belief in your life.
You can change paradigms by turning the reasoning behind upside down.
Paradigms most of the time start with the word " because ". By changing that, all of a sudden the reasoning, the belief changes. The starting point changes, and by that you can shift old believe systems, old paradigms into new and different, more true, starting point.
Or, as a friend of mine always says when I come up with a reasoning: " the opposite is also true"
