How to make yourself more self-controlled?

Usually, people will lose self-control in the face of temptation. For example, playing video games too much, getting up late and even masturbating too much are also manifestations of poor self-control. To enhance self-control, one way is to take part in physical exercise regularly, experience the hardships of sports in physical exercise, and enhance self-control in sports. Also, when self-control is poor, think about the consequences of doing so and imagine this scene. The truer the better.
