I recently drafted a post about how I was doing during my “midlife crisis.” I also dispelled some of the rumors of what a midlife crisis is, at least for me.

As I continue to grapple with the fact that I am 42 years old, I am making some pretty important discoveries.

One of those important discoveries is that I have discovered one of the key ingredients to living the life of a happy father. I discovered how you become rich and how that changes and focuses your life on what’s important. I’ve decided I want to gain even more wealth than I have today.

The kicker is for me being rich has nothing to do with money. For the busy father of five kids, the currency most valuable to me is time. Time to spend with my family. Time to talk with my teenage daughter about relationships and growing up. Time to explain to my son cleaning his room and doing chores isn’t a hassle, it’s an education in responsibility. Time to give my 4 & 2 year old a piggy back ride. Time to hold my newborn son and look in his eyes and share goofy grins.

Time. It’s more valuable for me than gold.

The issue with this knowledge is it’s hard to keep time in the bank. When you’re the sole provider for your family, you work and you sacrifice so that those kids can have a nice home, food on the table and whatever else they may need. You travel for business and enjoy your career yet yearn to be home in the middle of the madness.

All of my kids are important and they’re all at vital points of their development. It’s hard to devote the time. I guess my desire to be there as much as possible weighs more on me than it does them. Yet I can’t shake the fact I need more time to spend with them. Who knows how much time we have on this Earth.

I want to win the time lottery. I need more time for my kids and I need more time for my wife.

I’ll do more on my end to create and reserve the time but don’t waste any yourself. You can buy another house, a car, a sweater, an iPad – you can’t buy another day.

Invest in the most valuable currency a man, father and husband can – time with those that you love.
