I read that quote from Donn Felker a few years ago and didn't think much of it.
But now as a dad myself with a second kid on the way, I came across it again and it actually hit me, hard. My son is 2 years old and most of the time that I will ever spend with him will happen over the next 16 years (and years go quick!)
So here's how I'm making the most of it:
Prioritize spending time with them
There are many priorities in my life but spending time with my family is on top of them. I currently get home from work at 6PM and until bedtime it's family time. Cooking, eating, playing and the night routine are all things we do daily as a family.
When you are there, be fully present
During family time, no distractions allowed. The phones are put away and screens are turned off so we can be 100% engaged with each other. It was challenging at first but now it's just part of our ritual.
Create family traditions
We prepare something specials for each holidays, as well as an outside activity per season (for example apple picking in the Fall or visiting a petting farm in the Spring.) This is what we want our kids to remember later, experiences over things.
This quote was initially aimed at 18 years old about their parents. I switched it around from the parent's perspective but it really goes both ways.
Make the most out of your time with your loved ones, you will never regret it.
