Etymology

誠 combines 言 (speech, words) with 成, which likely contributes the sound and the idea of completion or becoming. Together they suggest words that are fully realized or true.

Meaning mnemonic

Words (言) that are fully formed and complete (成) are sincere and true. Picture speaking only when your thoughts are fully formed, so every word is honest.

Reading mnemonic

For セイ, imagine a sincere person saying 'say' with complete honesty: say -> セイ, and their words are always true.
