I have a one year old and this is such empowering advice. I discovered a lot of this on my own somehow, but reading that blog now reminds me to cut the bullshit that somehow keeps creeping back in. When explaining to my boss and peers why I was quitting my dream job, I would repeat, "life is fleeting, I want to watch my son grow up."
I've had that wish for a few months now. I have another job that's a bit less rewarding but I work from home and it's far more relaxed. I've already remarked to myself or my wife a dozen moments that I would have missed if I was elsewhere that day: at work, in traffic, etc.
I feel so blessed that I was lucky enough to figure this out this early in life.
