I think people are motivated to do that which they find purpose and meaning in. Because if one can spend hours together in playing video games, I think he or she is driven to play video games and finds meaning in it – could be atleast pleasure that they get from it. While if they’re not adequately intellectually challenged, if they don’t have agency at work and if they don’t have a clear why for doing what they do, they slack and procrastinate.
Addressing the root cause of procrastination then perhaps helps solve it instead of just thinking we’re lazy.
