Adults, who had self-control as kids, were able to suppress impulsive behaviors, persevere difficult tasks and had a successful career later in life.

The researchers explained that people with low childhood self-control experienced a pronounced spike in joblessness, lost their jobs and found it more difficult to regain employment during 1980s British recession.
Michael Daly, lead researcher, said that less self-controlled children might get vulnerable to unemployment during times of economic downturn in later life, whereas developing greater self-control in childhood helps one to buffer against unemployment during hard economic times and bring long-term benefits to society, through increased employment rates and productivity.
The study suggested that less self-control could be attributed to a range of factors including a heightened vulnerability to stress due to unemployment, the adverse effect of prolonged career interruptions on skill development and a greater likelihood of falling into habits which hinder their chances of regaining employment, such as poor time management and irregular sleep patterns.
