No. I'm a Christian and humanist you insensitive clod :)
Really and sincerely I do not.
If there's one philosophy I could share - that's given me a truly
awesome life filled with gratitude, meaning, mostly decent health,
intimate human relationships and personal agency it would be look for
the riches you already have.
I'm sure you personally get more happiness by not doing (too much) more than necessary, but as a "Christian and humanist", aren't you asked to do more?
You can replace "being rich" with "helping others", it still applies: you can trade comfort, sanity and health for more output, whether that's money in your account or helping those in need.
If you aren't born rich, breaking out of the working class, even the top tier of it, requires significant effort and enormous luck. It's usually time and effort wasted in pursuit of something no one should want. However, if you dream of sitting atop the pyramid but you weren't born there, you better get on that grind.
