I was a workaholic. Architected the First Mac-based Render Farm. Steve Jobs knew of and was going to talk about my work...
And I have almost no memories of the first 3 years of my kids lives...
Whatever choice you make, just know that the time that they are kids is time you never get back. Well, you never get any of it back, but you can't make up for time missed. I'm painfully aware of this as due to my migraines, I miss a lot of concerts and recitals and what not. I'll never ever get another shot at those.
Money is a means to an end, it's not the end. When you really just sit down and focus on what's important, the answer should reveal itself.
