Hopefully I'm not doing much violence to the text/intention or mixing various passages, but in Seneca's Moral Letters (100% there and 95% in a letter number < 100) there is a passage where he says (or brings the complaint of his penpal) something to the effect that some might achieve something easily and without a lot of work. I think the word for achieve/getting/come to them was somewhat notable to me (so not contingere and probably active plural)
can't find it. With keywords I keep reaching letter 88 which is not there.
