You should play options.  Set aside about 20-30% of your portfolio and learn.  If you have specific questions, feel free to PM me.

If you've got a recommendation for some literature on the fundamentals of trading options I'd appreciate it.  I understand it on a very basic level but that's about it.  I've got an engineering background so I enjoy playing around with numbers. 
  
 Aside from my retirement account I've got the bulk of my savings in cash and I plan to invest most of it in Vanguard ETFs.  I've got around 10K to play with on Robinhood (lol)
