This is the top indicator of success

If you want to get ahead in life, you need to have self-control.

A number of studies have found discipline is the top indicator for success in various fields, including education, job satisfaction and personal relationships.

In school, a 2005 study found self-disciplined individuals outperformed their peers across a number of academic variables and were most likely to improve their grades.

The study concluded:

Self-discipline has a greater effect on academic performance than does intellectual talent.

Self-aware and disciplined participants in studies have also previously reported higher incomes and job satisfaction, and have reported longer, more satisfied marriages.This week, research published in Trends in Cognitive Science found that self-control is also the key to giving up smoking.

Research has also shown increased conscientiousness is also associated with living a healthier, longer life.
