> but also recognise that your brain/body only has so much "fuel" each day ... My experience is similar to yours, and I would also add that that "fuel" grows if you maintain the effort throughout the days/weeks. But some of the days you'll have more fuel, others less, just to the best you can (I struggle a lot to keep that balance, not easy at all..)
