Definition of Equality

On my run tonight, I was having some mathematical thoughts. It went something like this. From day to day, Elli changes little. However, from month to month I can see definite changes. From year to year, it seems impossible that I missed her growing up. So, 1 day + 1 day = 5 years. Then I was thinking that 5 years + 5 years = 18 and heading off to college. Then it hit me again, 18 years + 18 years = 40 and independence from Brent and I and hopefully her own family. While I was processing that, I realized that 40 years + 40 years = eternity. So when I apply the definition of equality, 1 day = eternity and what have I done today to impact my little girl's life for eternity? It just so happens that today was a good day for eternal prospective things, but then I reminded myself that 1 day + 1 day = tomorrow. What we will do tomorrow? For that, I must start planning today.
