At a given moment in your life you have to focus on something. If you have a deadline coming up at work, you have to focus on work; if you marriage is suffering, you have to focus on your spouse; if you mum is ill, you have to focus on that;… There is no such thing as life-balance!
You might live in a life-balance situation just for a small moment but you can’t expect it to be a way of life, reality will happen as soon as you get out of head.
