agendum

Tum id agendum est ut ante caput deinde reliqua pars auferatur.

Et ad similiter agendum etiam alios inducere diligenter studuit.

For God's sake, aim at perfection in everything: 'Nil actum reputans si quid superesset agendum.

Et quiescenti agendum est, et agenti quiescendum est—He who is indolent should work, and he who works should take repose.

Nil actum credens, dum quid superesset agendum—He considered nothing done so long as anything remained to be done.
