The word "earnest" seems a bit antiquated to me. I've rarely used it since I was a child, except in the phrase "earnest money". https://www.investopedia.com/terms/e/earnest-money.asp https://www.investopedia.com/terms/e/earnest-money.asp I guess "honest", "dedicated", "non-flaky", "good follow-through", and "good track record" would be terms I would use to communicate it instead.
