My son turns four this month. Here are four things I've learned in this time of fatherhood.

Purpose

My life has one now, not quite sure if it did before. One of the beautiful things I've learned on this four year journey so far is that I want to be the best version of myself for him. He pushes me to eat well, to workout, to do the work on myself. I want to be around for as long as I possibly can so I can grow with him as he grows with me.

Time

When you have a child you see changes so often, both mentally and physically. The idea of time flying by becomes this tangible concept. It's kind of nuts how much faster time seems to go these days. I'm trying to enjoy every moment as best as I can.

Patience

You think you're a patient person? Have a kid and then let me know. The exercise in patience is quite something. Some days I'm good at it, others I'm not. The important thing is that I'm aware of it and always trying to be better than I was yesterday.

Laughter

It really is the greatest medicine. The stuff this tiny human says is remarkable. He's so free and so alive and so in touch with what it means to be human. Being the father to a small child reminds you of what life was like before society shaped you into something you may not have chosen for yourself. We are all just children in adult bodies. Play, be free, love one another.

Ultimately, he's probably teaching me more than I'm teaching him. And for that, I am eternally grateful.
