A productive day isn't just about what you will do, but also what you won't do. That's why Jack Dorsey, the CEO of Square and Twitter, lists out what he will and won't do at the start of each day.

Dorsey shared the strategy in a recent tweet. On that particular day, Dorsey listed some priorities. He decided he would meditate, read the bestselling non-fiction book "Winners Take All," consider Twitter's metrics and write his notes regarding the dining experience for users of Caviar, the delivery platform Square bought in 2014.
