Your EGO can easily work against you or work in your favor. Your EGO never really dies , it just matures with time , experience, acceptance and healing. Many people believe that they cannot use their ego to their advantage but they most definitely can. Sometimes the true authentic version of us , is living in the shadow of our EGO and we don't even know it. It can supress who we really are because we're afraid to be who other said we couldn't. Those feelings of not being good enough, hurt you so deep that the EGO had to step in to protect you. But instead of acting as a guiding force of assistance it is now , suffocating your true nature. In order for the real you to re-emerge, you would have to heal that mask that's kept you from feeling for so long.
