(the) frequent use

Could you correct my English?:

-He is very perceptive in making this remark. In daily life, very often those who pay the greatest effort are neglected; writers become famous by studying, which process involves (the) frequent use of dictionaries, but dictionary writers are never celebrated; a singer shoots to fame by a euphonious song, but the composer's name is almost never mentioned; an actor receives the highest reward of his profession probably for several lines he uttered, but the script writer is still living/still lives in the dark. These are interesting phenomena.(I know the editing system here doesn't lend itself to efficient correction; so you could just copy and delete a few words as the best version you think it should be)

Thank you.
