Are you so much a slave that you have to search for meaning in the nobility of work? Work does not offer us purpose because there is no purpose in the operation of institutions in the modern world. Where the driving philosophical principle of an enterprise is "make as much money as possible", who among us can wring out a meaning that satisfies us spiritually?
Where even our charities are corrupted by the guiding principle of more money more good - from where is the conscious worker to draw their meaning?
We exist in an age of spiritual and moral vacuum and there is no guiding principle at this time that a non idiot can align themselves with while retaining some semblance of internal consistency.
How is Elon Musk working magic? A big part of it, apart from not being just another idiot with an MBA, is that he is giving people an actual purpose they can get behind. A purpose that is not just something slung over a money making machine in a vague attempt to align the workers. No, a real bottom up purpose that drives the enterprise. With that kind of purpose a team can move a mountain.
You have to ask yourself... If you are not trying to save the world from cooking itself, or trying to end poverty or trying to cure cancer, or trying to ensure the existence of humanity into the far future, what the bleep are you working for? Answer: You're working for the thoughtless vacuous industrial machine that is devouring both our souls and our physical world.
You should be depressed because this sh* is depressing. You should be angry because this sh* should make you angry. These emotions are deep intuitive reactions, they are drivers for change, hear them and move to change the way you work.
