I think that, we shouldn't try to strenghten our weak functions. They are weak and will become weak even after the training. It's much better to try to make our 5 and 6 function stronger by finding dual and then thanks to dual our 3 and 4 function will become stronger cause of your duals protection. But trieng to live by using your SUPEREGO block will only make you feel uncomfotably and make you have stress.
