* 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.
