Play poker once a week for small, but real money. Study the game (read Sklansky, Harrington, do the MIT poker school).

After a year, you get used to the idea of a bet where you'll win some, lose some, but know on average you'll do better than OK.

Investing is gambling, but with an edge, since it's not a zero-sum game. Also you have to be patient, you are almost certainly not going to consistently beat the market short term, but you should do better long term than not investing.

If that's not for you, then just buy target date funds, balanced funds, structure your own balanced ETF portfolio, or pay a robo-advisor or human advisor to invest for you.

TFA's type of trade is like advantage gamblers who read the fine print of casino promotions looking for situations where they have an edge. Whoever sold that (presumably) OTC exotic bullet option (probably) didn't realize leveraged short vol funds forced to cover could create a vol-pocalypse. http://kiddynamitesworld.com/xiv-volpocalypse-sea-disinforma...
