You need find meaning in _life_, not just work. Why are you here? You know you aren't the first person to hit this problem.
Religion offers a solution for this problem, when the purpose and value of your life is more valuable than your day to day activities, your money or anything you experience now.
But most people will suggest therapy so you can learn to be happy with what you have already become unsatisfied with, worldly success.
Go find unhappy people and help them. Poor, destitute, maybe a sad neighbor, and do something for them. Then maybe you will find a new thing in life worth caring about.
