You certainly do have a lot going on - raising kids and attending college - that's enough for at least two people. Good luck with your decision to make healthy food choices. Hope you stick with it for a lifetime.
Any weaknesses you care to share? As for me, the lure of the discounted Easter goodies in the convenience store is really tough. It's hard to pass up such a bargain (50% or 70% or 90% off). Then I can't stop eating the bag. Time to change that habit.
Good luck to you.
