sedulous

A sedulous person is someone who works hard and doesn't give up easily. If you make repeated and sedulous attempts to fix a leaky pipe and it only makes things worse, it might be time to go online and find the number of a plumber.

There are a couple of words that basically mean the same thing as sedulous but are a little more common, namely assiduous, painstaking, and diligent. Like sedulous, all of these adjectives can be turned into adverbs by adding the suffix ly: "He assiduously tried to fix the pipe, but to no avail."
