What to do if you have inherited weak willpower?

The most important thing is to understand and accept that this is who you are and it cannot be changed. If you know that you are prone to impulsive behavior, you will struggle to resist any temptation through sheer willpower. However, this does not mean that your life is over and you are destined to become overweight, addicted, or lose your job because you will continuously binge-watch TV series. Instead, you need to utilize your weak-willed mind not for exhausting and futile resistance to temptations, but for planning your life in a way that minimizes their impact.
