Trust me you are not the only one
It is very hard to juggle work, marriage, kids and training but I try to do the best I can. Most of the time I plan the majority of my meals the weekend prior and bring my stuff with me to work. Training is normally 3-4 days per week and I come in early in the morning so I can afford to head to the gym at about 1500 so I can be home by 1630 for the family.
Tough but worth it. Just need to get more sleep and less hassle from the wife. Wish me luck.
