There is no question that being a surgeon will take a huge amount of time away from your family or social life. This can be especially true during residency. Although working hours now have a maximum of 80 hours a week (still double the traditional 40 hour work week), many residents will still find themselves working more. However, you can always arrange things to accomplish your personal goals with family and investing in your own wellness. Many surgeons have families, take vacations, do triathlons, etc.
The big point I'd drive home is that you cannot always commit time to everything in your life at the same time. Sometimes work will come before your spouse, and other times your spouse will need to come first. It is important to find someone that understands this balance of time and the commitment you have made to your patients.
