The people around you can make your life difficult. Once you notice this, you could take (unconscious) action to defend yourself against these threats. Defending is reacting to actions of others. However, some do not accept others to set the boundaries for their life and they decide to take the opposite route to freedom, the offense. All of us have the creative and aggressive power to create the life you want, instead of allowing others to limit you in any way. You just need big balls.
