Thina

"Bhikkhus, the lazy person dwells in suffering, soiled by evil unwholesome states, and great is the personal good that he neglects. But the energetic person dwells happily, secluded from evil unwholesome states, and great is the personal good that he achieves. It is not by the inferior that the supreme is attained; rather, it is by the supreme that the supreme is attained. Bhikkhus, this holy life is a beverage of cream; the Teacher is present. Therefore, bhikkhus, arouse your energy for the attainment of the as-yet-unattained, for the achievement of the as-yet unachieved, for the realization of the as-yet-unrealized."
