According to Wiktionary, the meaning of the adjective 'painstaking' is 'carefully attentive to detail'. However, I am having difficulty comprehending what exactly this means.
Consider, as an example, the below sentence, taken from the Webster dictionary site.
She was always painstaking about her work.
What might this entail? For instance, if she were a researcher, how could she be 'carefully attentive to detail'? My mind is blank.
