Hm. I thought a bit. Looked through the list. Thougt a bit more and concluded: I'm quite happy with my learning curve,

Only after looking thru the comments did I consider Investing. Advanced Investing actually. That would have been handy not only because of the money but also for more interesting job opportunities. Problem is only that I'm not clear how I could have had a path to that knowledge.

I'm quite happy that women and style knowledge are placed so late in my life. The mastering of these can eat insubordinate amounts of time and effort and cannibalize other areas.

I', very happy that math and the sciences came first (and deep) and have made learning all the other areas much easier.
