Procrastination is likely my life ... but it's true on the subject of energy, too much negating leaves also some marks and leads to lose the "maximal energy capacity" I think. But I know for my self that there are so much things I can do whiteout the felling of draining him self, it's likely the opposite. Like a temporary boost in the capacity and endurance but it also has it's downside by faster loosing the focus on "why" we do this.

(I'm just sharing my past experiences but it's also it's mostly true to others) (Sorry for some leaps on my side but I wouldn't stretch this too much)
