I agree with everything you're saying except for your usage of purpose. To me, life is not about doing meaningful and purposeful things. It's about satisfying yourself. With the right incentives, we can satisfy ourselves in ways that are meaningful and purposeful. Finding the right work with the right people is extremely satisfying. If you don't enjoy your work, it's likely you are not working on the right things or you have some mental health issues which are lingering beneath the surface.
