0 to carry on doing something at the same speed or as well as one is doing it at present -- ¡sigue así!, ¡ánimo!
We can complete it step by step however long the road is and it can't be completed however short the road is if you don't even mark your footprint.
Podemos completarlo paso a paso, por muy largo que sea el camino, y no se puede completar, por corto que sea el camino, si ni siquiera marcas tu huella.
