Thanh, because I believe work supports the family, I am willing to sacrifice work for the family but not vice versa (it's been a difficult but rewarding choice because it challenges me to work even more purposefully).

When making choices, I ask myself how does my choice affect my relationships (key word) in this order of priority:
1. Family:
a.Spouse
b.Children
2. Work:
a.Team
b.Strategic Partners
c.Customers

With honesty & often the help of mentors, I consider my motivation and the pros & cons of my choice. If a choice has a negative impact on the family, I would find alternatives or simply say "No" to the opportunity.

It's taken years of painful mistakes in the past for me to come to a decision to choose family over work. In the work, it's also been many painful mistakes to come to a decision to put the team before customers.

These priorities have now helped me to make better choices - which leads to more peace, less regrets and balance in my life. Hope this answers your question :)
