If you are trying to compete with people who are kidless and constantly comparing your output to them, then yes, you are going to feel you are falling behind. But you need to stop and ask yourself, “what am I doing all this work for”? What is your goal? For me, having children changed my perspective on life. I am lucky to make enough money to live a good first world lifestyle and the rest is enjoying the moments life brings. I still have the motivation I had 20 years ago but that motivation has shifted from “building things for the wealthy” to building peace and happiness for myself and my family.
I no longer work a ton of hours, but my day is still full of conversations, walks, work-outs, bike rides ect… These things when done with family and friends bring me level of accomplishment that no product launch ever did. Also, I openly avoid the hustle-grind culture that seems to run rampant these days.
You seem to be on the correct path, just don’t fall into that trap that says you must be grinding 60+ hours a week in-order to be successful or happy. It will find you if you let it.
