Working in a team. Social pressure is one of the biggest drivers of self discipline. If that seems hard to believe think about those who join the armed forces. They cultivate discipline because they want to help their team to conquer over the enemy. Their loyalty towards their teammates is at the forefront of their actions. They strive towards a cause that’s greater than themselves. If they don’t practice self discipline to work cohesively they will not be able to be of service to themselves or others.
