I've shared this before in a previous thread but I'll do so again: https://wall.org/~aron/blog/

This blog has had a huge impact in my life and I'll be forever grateful to Aron for uploading it to the internet and also grateful to Fede_V who shared the blog in this HN comment a few years ago: https://news.ycombinator.com/item?id=18176929

My life is much more fun and fulfilling thanks to its influence.

There are lots of other great blogs but none have had as great of an impact on my outlook.
