Being stubborn is a weakness.
If you are stubborn in ateas that you know will get you to nowhere, then it won’t do you any good. Yes, sometimes we need to stick to what we know. The main point is if by being stubborn does not help you, improve you, does you good, then sticking to your stubborness is non beneficial.
Stubborness is a result of what one beieves in and refuses to change. If it affects your life negatively or disempower you, now it is time to use your conscious mind to make a decision to stop it and then use a subconscious technique to help you to release it.
Using hypnosis to turn off your weakness and replace it with good traits is one subconscious technique.
