Being entrepreneurial is often an 'always on' state but it need not consume all of your thoughts and attention. Consider these solutons
1) Take micro-breaks that involve being mindful and 'in the moment' when you are with others. Carve out time, even 5, 10, 15 minutes while 'working' and do it frequently (every hour) and focus on other important tasks and people.
2) Practice better distribution your time, attention and energy as a way not to avoid your work but to enhance your ability to focus. Reading a report while on the treadmill can be efficient, reading the report while 'watching' your child's soccer time can be draining.
3) Create your own personal app that schedules an 'alarm' once an hour that says 'time out'. Control your own schedule by prioritizing what is important, and that includes you, your healthy, family and your business and bring a little more balance to your work/life.
