If man spends most of his time thinking about his temporal situation, why doesn't he invest even a minute amount of time on more important thoughts: What is he? Why is he in the world? Or what is The King of All Kings requesting of me? What it the purpose of everything?
This is the strongest antidote that can be fashioned against our inclination and it is so easy, yet its impact is so significant. All that is needed is to clear the mind from everything else for at least an hour to think about the aforementioned. Introspecting, one should ask, what did the forefathers do that endeared them so to G-d? What did Moses do? What did King David do and all the spiritual giants that preceded? These questions will breed answers that direct one to do good and in turn better ones life.
