From the time children are small, parents help them to develop self-control. Rightly so, we see this skill as necessary for success in life. Regulating their emotions and impulses allows kids to avoid getting in trouble at school and to behave well during religious services, birthday parties, visits to grandma's house, and play dates.
We can infer then that happiness is enabled by an ability to create at will what we need, mentally, emotionally and materially. Although this sounds like a hybrid of the Law of Attraction and great portfolio management, to measure success in this way is really determined by our levels of willpower and self-control, which when combined lead us to self-mastery.

Surprisingly, given the importance of employment to well-being and the global economy, the link between self-control and job success has not been thoroughly studied. Until now.
