One with "the dream job" can never be sure how much material he needs always in fear he has too much or too little and is constantly looking over his shoulder to see who is watching him, in fear they will find out his secret. The one who trusts in H'shem though knows he will always have exactly what he needs never in fear, eager to tell everyone the secret to his success. In addition, only one who trusts in H'shem can be certain he will be protected, healthy enough to be able to accomplish what H'shem has set out for him to do.

Nefesh Hachaim
From the time the Torah was brought down by Moshe to the lower worlds, "the continued existence of all the worlds is secured by our speaking and thinking Torah thoughts" We can understand from this that if GD forbid there would be one moment where someone in the world was not engrossed in Torah study "all the upper and lower worlds would instantly cease to exist GD forbid"
