Work-life balance is a term commonly used to describe the balance that a working individual needs between time allocated for work and other aspects of life. - Wikipedia
Work and life were never separate for me, but always intertwined.
Most of the time, I cared a lot about my work and was never resentful when I had to put in extra hours to get a job done. I got a sense of satisfaction from doing great work.
In my last (corporate) job, this caring about my work almost went a bit too far.
I was always on call and spend even Sunday mornings at work. I started dreading the ringtone of my work phone because it became synonymous with "something is wrong." I started crying when I realized I couldn't complete a job for a client even though it wasn't my fault as a co-worker had let me down.
Now, as a freelancer, work and life are, even more, blending in together. But in a good way!
I love this quote by @rosieodsey
I don't fight for separation between life and work any more. Instead, I fight to choose good work.
I feel that I've finally chosen good work and I'm more in control of it. That makes a huge difference - every day.
