I think Work life balance concept doesn't really work - because it puts the idea in your head that the time should be balanced between the two and that is pretty difficult to achieve (unless you include sleep on the life side) - I like to think of it now as minimizing work vs life conflict. I think I am at peace with the idea of working now, but it has taken a while and I have the added benefit of having had periods of not being able to find work and be very short of money which I can look back on whenever I think the 'is this all worth it' thoughts.
