I throw lots of time & money behind projects as a form of open-ended exploration. I often spend years pursuing projects with no apparent value.
I just pray for wisdom and continually ask "What is God's will?" as I'm deciding how to invest my most precious resource -- time.
I hope you live even better than me. I used a doc-style framework to help anyone quickly absorb elements they like. Feel free to suggest improvements on Github or Twitter, or even create your own fork (This site is AGPL licensed).
