Yes. There are also some good comments at a previous related discussion at https://news.ycombinator.com/item?id=18903886 .

I wrote some thoughts about finding direction in life (focused on learning for one's growth, and using that to serve others in some way), at http://lukecall.net (a lightly-loading web site). You can click on "Life Lessons" (4th bullet), then "Everyone needs a direction in life" (~ 6th bullet). It is in progress but I still hope it can be useful. Or the direct link is http://lukecall.net/e-9223372036854588981.html .Feedback welcome.
