Hi Jaleh, thank you for a great story. I've had a similar experience where I was always working late before my daughter was born but it took becoming a mother to give myself permission to leave the office at 5pm. Like you, the impact on my productivity has also been extremely positive. Knowing that I have to stop at 5pm makes me focussed and I question the value of each meeting I attend. I think this ruthless efficiency and productivity this is an under-appreciated trait of working mothers.
As a new writer for Medium, you've inspired me to share my experiences.
