How big is your briefcase (if you still have one)?
When you think of taking work home, do you just fill your bag (ipad, usb stick or whatever) with files and documents because you "need" to and then never actually do anything with them at home or get home and work like a slave for hours?
If you do either of these, try this simple technique:
Say to yourself, "How much of this work could I do if I stayed here for an extra hour with no interruptions?"
Sort that work out, put it to take home and when you get in and have de-stressed from your journey, greeted your family or whatever you need to do, take that one hour of work and do it for one hour ONLY! If it takes you longer than an hour then you either are underestimating your work or overestimating your ability - be realistic!
One hour completed is far better than none or hours and hours, leaving you with no time for "play" and leading to resentment by family friends and yourself.
Balance is key to happy work and play
