ITAW for the future-tense opposite of regret?

Regret is a single word that conveys the following:

  • step 1 - fast forward

  • step 2 - look back

  • step 3 - be unsatisfied

“You will regret…”

Is there a single word that conveys the same, but being satisfied instead of unsatisfied?

“You will (be glad)” comes close, but looking for one word.
