Achieving a work life balance is quite challenging because it is a continuous process of setting priorities and discipline oneself to set boundaries for work related activities. For some people they can no longer tell the difference between their work life and personal life anymore and it has affected their relationship with everyone around them.
There is right time for everything, no matter how difficult it might seem, just like you said a person must find a way to balance their work like to ensure a healthy lifestyle.
this is a key note that you have mentioned here, and discipline makes it possible.
I like your addition that for everything, there is a right time.
