The barbell strategy

The barbell strategy was introduced by Nassim Taleb in a book called "Black Swan". Taleb states that you should allocate 85% of your investments into safe bets, and dedicate the other 15% to bets which have high risk, but high rewards.

One can extrapolate this to other aspects in life, like time management, creativity, etc as stated here: https://kadavy.net/blog/posts/barbell-strategy
