Quality of Life
I am currently switching to another company, and a big influence was "quality of life." I am taking less pay, but drastically shorter commute and more time off. Granted many things went into the decision, but having a wife and a 2yr old little girl was probable the greatest influence. I will save an average of 2hrs a day on commute, and that is an extra 2hrs with the ones that really matter. I wish I could see her all day everyday, but that is not life, so the more I see them the happier I am as a person.
No matter how bad my day is at work, I know I can come home to a child that can brighten my day with just a smile. That could change when she is a teenager, but for now, I'm good.
Last thing, I like what I do, but it is not who I am, my family will be my legacy.
