Enemies are the opposite of friends. Your enemies do not want to help you or work together for a common goal, instead these people dislike you intently and they want nothing more than to see you fail or to make you suffer in some way. Some enemies are made as a result of your actions, but in other cases certain enemies may be the result of the actions of someone else. If your spouse is cheating then the third person may view you as their enemy because they want your spouse.
The saddest thing about betrayal is that it never comes from your enemies.
The secret of change is to focus all your energy not on fighting the old, but on building the new.
