Like intelligence, people can grow their self-control.

Self-control is controlling one's own responses so they align with short and long-term goals. Self-control is about harnessing your energy toward a particular end goal. For example, someone displaying self-control can delay a short-term temptation to play games on her phone if it interferes with her long-term aspiration to do her homework each night.

But, self-control is hard. For example, in the next step you will watch the video of young children trying to stop themselves from eating the marshmallow in front of them, with the hopes that if they wait and do not eat it right away, they will be given a second marshmallow.

Scientists have discovered that by trying new strategies, learning from others, and practice you can improve your self-control ability. The great news is that self-control can be increased.
