My Dad died in 2001.
Of all the life lessons he modeled, I think the greatest was how he approached each new day for what it was; a new day.
He never seemed to harbor/carry over grudges and always seemed to remain positive in regards to life, no matter what financial or health stress he was dealing with at the time.
For any Fathers out there estranged from your kids, reach out to them again.
Say you're sorry or forgive them for any transgressions.
It's been overused but it's still true nonetheless: today is the first day of the rest of your life.
If you're a Father, but haven't really been a Father, re-start now.
Being a Father is a blessing.
