Live a life of bitachon and emunah in Hashem (faith and trust) when a person’s entire life is around bitachon and emunah then you get to be the happiest person in the world cause nothing in the world can effect you. EVERYTHING in your life from your health to livlihood and family etc… Is ALL around Hashem the king of kings and ruler of the world. And not aroaround your job, Rebbe or doctor etc…. These are all middlemen and just agents of Hashem but ONLY HASHEM can help you with anything from health to livlihood to happiness etc….
