G'Day, recently I was invited to contribute to a great book called Balance: Real-life Strategies for Work/Life Balance. Now my opinion is ... there is no such thing as Work Life balance... I think it is a myth.
What I do beleive is that we can achieve Work Life integration by assessing our environment, emotions and expectations.
If you want to be more productive, stop chasing the elusive 'balance' quest and think about how you can integrate more aspects of your life. Stop compartmentalising everything and integrate. Find out more of my thoughts on this topic at www.neenjames.com
