Through HN (and PG's) essays:

- Insight to plan 1 year sabbatical (financially and technically)

- Shipped a 3D game from ground up in that sabbatical, learn 3D graphics was the objective of that

- Got a scientific developer job as a result of that game, part of which was to contribute to OSS Libraries

- Now working as a freelance 3D graphics engineer

- Introduced me to Lisp which I have used ever since to learn hard topics

- Wrote a 3D asset kit for iOS, which is open source.

NONE of the above would have been possible at all without HN (and PG's) essays. Thanks a million!!!
