I'm a "career person" and expect to retire soon in my late forties. The blog's advice is generally on point, but IMHO places too much emphasis on busting ass to play the career game. There are easier ways to win, and here's my secret sauce:

* Get a job at a successful listed tech company (not a startup) that issues RSUs.

* Get promoted to senior level but no higher (too much responsibility, poor work life balance, exposure to office politics)

* Move to a low tax jurisdiction like Dubai, Hong Kong or Singapore, at least long enough to build a serious nest egg (several million).

* Live significantly below your means: I aimed to save & invest half my income. You'll still live a good life because these countries have vast income inequality and services are cheap.

* Find a partner who shares your values.

Not saying this is easy or even possible for many, but it worked for me.
