Consistency and constancy are the hallmarks of disciplined work, which aims, little by little, to sink a well and tap deep, otherwise inaccessible, energies. Such work is difficult because for long periods there will be no seeming reward and the student will be tempted to desist, hence the need for constancy. And for those driven to seek, the temptation will always be to try new things, in which case they will be perptually scratching the surface, hence the need for consistency.
