Four steps to finally get what you are supposed to do in life:(according to Voltaire's Candide)

1. Mind your own business

"Is it your business?" (141). - dervish

"I have no idea" (142). - old man

2. Don't worry about little things

"Do you suppose he worries whether the ship's mice are comfortable or not?" (141). - dervish

"I never bother myself about what happens in Constantinople" (142). - old man

3. Don't try to figure things out that don't really matter.

"Keep your mouth shut" (142). - dervish

"That's enough for me" (142). - old man

4. Keep yourself busy with work.

"...slammed the door in their faces" (142). - dervish

"we find that the work banishes those three great evils, boredom, vice and poverty" (143). - old man

So, that is what I got out of Voltaire's Candide.
