Show HN: The Importance of Positive Energy [Open Source Book]

I started this open source book to help people feel better. Please check it out and contribute if you'd like :)

I'll get it published with all author names once we decide on finality, and we'll share donations with contributors through Bountysource! https://salt.bountysource.com/

Even if you don't want to contribute, please star it to help yourself be more positive in the future.

Best, Kendrick
