This is the age old question. If you figure it out, let me know. I think the key to this is balance. You need a good balance between work and home, and i know that's easier said than done. Setting your priorities and sticking to them is a key. You need to put certain hours aside when at home which are considered non-work hours. These hours should be dedicated to family and kids. Once the kids go to bed, then you are free to go back to working. It is important to have that special time set aside for family.
