The biggest mistake is that we are wanting something or someone to act in a certain way to make us happy . This is happiness that is undependable and it leads us to attempt to control others and life. Good luck with that !! All upset comes because someone didn’t do it our way,which we think is synonymous with the right way. As the Buddha once said it is the happiness that comes from within that can’t be lost. Healing the biggest mistakes leads to a whole new level of emotional maturity ,which regains more of our heart. This leads to partnership and new levels of success and intimacy.
