applying oneself to something known to be within one's ability
Original Dramatica Definition
When a task lies within one's known abilities, effort applied to the task is Work. There are no surprises; no short-comings. But has one accurately judged both one's abilities and the demands of the task? If not, perhaps the task is not achievable or of a size that one must increase one's abilities before undertaking it.
syn. appropriate undertaking, suitable task, manageable labor, a performable activity
