I think a good way of reframing it is to change "wasting time" to "cooldown time" or "rest time". You don't need to be doing something "productive" all the time

I think a good way of reframing it is to change "wasting time" to "cooldown time" or "rest time". You don't need to be doing something "productive" all the time, it's fine to allow you time to do unproductive sutff that you enjoy. It also allows you to really enjoy it, instead of constantly telling yourself "I should be doing something else"
