Waste

Nulla dies sine linea, said once painter Apelles. It means that you should not allow single day without "a line." It is important to realize that procrastination and delaying is just how our lazy mind and body works. But we have to transcend them and become active. The path is painful and tiresome, yes, we will sweat the blood by the end of the day. But realization that we have made some progress could keep us warm for at least one day.

The taste of time well spent is better then bitter tea made from the wasted time.
