I don't like the idea of separating life and work. That notion seems dated and a bit alien to me.
How could you not let your life affect your work? That's all it is. Unless you have a very specific, isolated version of what you're doing.
As soon as you take your hobby and make it into your profession, it sort of kills it as a hobby.
I have a very clear separation between my life and my work.
I tend to be a bit of a workaholic, but I also can't function without some sort of domesticity as well.
I don't believe that you have a work life and a home life. I believe that you have one life, and either it's working or it isn't working.
Some people make sharp distinctions sort of between their recreational musings and their professional work. I don't make that distinction very much.
Sometimes, when my wife and I were going out to dinner, I would take my laptop with me and work in the car, so as to take advantage of the half hour going and coming.
I am very much married to the job.
I simply do not distinguish between work and play.
Part of the way the work world works is not so much creating a separation between your work and your free time, but creating the illusion of a separation between your work and your free time. Every day is the weekend for me, which means I'm always busy.
