Hello,
The short answer is by getting your priorities right.

And for that you need to have your criteria properly set.

I have developed an instrument that takes into account the most important areas of a person's life:
- health and energy
- relations
- growth & evolution
- and of course... career

The simple answer is to set boundaries between these 4 areas and not cross them...

In my 5AM Coaching program I offer the following daily structure:

5AM to 7AM (Me time - exercise, water, breakfast, priorities for the day, journaling, affirmations)
7AM to 8AM (greeting the other members of the family, preparing to leave for work/school/etc)
8AM to 9AM (travel)
9AM to 6PM (intense & focused work - following top priorities and other productivity methods (e.g. Pomodoro technique))
6PM to 7PM (travel home)
7PM to 9:30PM (family time and/or friends time)
9:30 to 10PM (me time - finishing off the day, lessons learned, priorities for the next day)

7 hours of sleep... and continue from 5AM on...

This schedule that I follow together with all my clients is the answer.
