Part of the training I have gone trough at multiple companies is to know when your tired and know when your exhausted. A very big dangerous difference between the two. Sleep debt as it is called catches up to you eventually.
Yesterday I pulled into a rest area on the way home for a nap. I woke up this morning with my boots on.. This flower was at a customer. I don't know what its called but I just really liked the looks..
Never ignore sleep.
