What is repenting? Repenting is charata (regretting our past doing). But at the same time, teshuva is: Where do you want to see yourself in the future? Think about it sincerely. Are my goals and priorities really to get close to Hashem? If you're real about it and you make a plan for how you want to grow and get close to Him for the upcoming year, to Hashem, that is teshuva.
We're learning from you that it's never too late, because Hashem wants people to do teshuva. So He picks them up all the way close to Him in spirituality as long as they're alive.
