To be clear, a job does not give your life meaning. How you treat people and how you relate to communities and society is where you get your meaning. Work is just a great platform to deliver that meaning. You can choose whether or not you make your work meaningful. – edited from Penelope Trunk.
A very nice note by Trunk. It's true, coz if you're not influencing someone in the world positively, you are literally an invisible entity to other lives = a life without meaning, like a desk is even more meaningful than you do, at least it serves others well.
