This is always an interesting topic. I’ll go straight to the punchline – you will very rarely have a harmonious balance.
What can I do?
If the kids are off on half term then the work pedal can’t be full throttle.
Or when your dissertation is due in a month, your social pedal cant be on full throttle either.
But you can set some rules that you feel will give you a sense of balance. It might be that Sunday is always a work prep day or on the other hand, Sunday is strictly Sunday Funday!
Other rule setting is setting an alarm to shut you out of emails at 7pm each night – in fact I believe in France it is illegal to conduct office based work on the weekend. I remember when working for L’Oréal and we all got locked out of our computers at 7pm each night.
Balance is flexible, and for here for you to design.
