Congratulations! Just saw this thread.
You are so young and have such a phenomenal household income (and really, budget is pretty outstanding too), if you don't creep up, you are going to be rich before you know it.
The biggest adjustment you may have to make is if you don't have children and plan to have them in the future. Kids have a way of really modifying your budget. (i.e., your "go out" budget becomes 0 for several years, but your clothes, toys, food budgets all go up.)
Have you thought about setting a goal of a specific $ amount per year to invest/save? Say you want to increase your contributed principal of investments by 100K per year or whatever. Then you can count it down each month. Something like that may help you stay on track over the long haul. Almost the reverse of paying off debt a-la Dave Ramsey. (But for more badass people:)
