They are great with timing
There is nothing like understanding perfect timing. Diddy wisely invested in Ciroc instead of just being a spokesperson. Dr. Dre got into the headphones business years before it exploded. 50 Cent put his money on VitaminWater before it was bought by Coke. Jay-Z sold Rocawear clothing while at its peak. And Birdman was able to keep Lil Wayne on his label and signed Nicki Minaj and Drake. Perfect timing is all about understanding the business and having awareness on what will occur next.
