Put your best foot forward.

It can be tempting to give less than your best effort because we all have an inbuilt tendency to conserve our energy. It is very easy to get into lazy and slovenly ways but we never know when someone potentially beneficial to our lives might come by and judge us on what they see. So it is best to keep your standards as high as you reasonably can, though common sense tells us that stressing yourself excessively and worrying all the time about performance could ultimately be counterproductive.
