But towards whom? If you are responsible at work, sometimes you do more than will be appreciated and your family might suffer. But if you do not do it, your colleagues might suffer because something will not work properly.
It is the core of life finding balance in life. What we usually forget is ourselves. Being responsible towards our own life, needs, psychological and physical well being.
Is it worth the sacrifice? Sometimes it is, sometimes it is not. But we rarely stop and consider this, we just get ourselves taken forward by the events happening around.
