If an individual wants to attain power they must be able to ignore the angry reactions that others will harness against them. For some will act out of jealousy and it’s important to be strong against such reactions when power is needed to achieve a goal. Yet the more one hardens their heart the more they will not see or feel good advise that can come from deeper sources as well. If Pharaoh originally would have listened to the simple signs G-D was sending him then the major damage to his kingdom would never have occurred. It is important therefore to be strong when you feel you are right but still be stronger enough to admit when your wrong. Power can be one means to achieve a goal but when it is your only goal it will eventually bring you down to a state of truly becoming powerless.
