I like how @HImom tracked expenses in those young tight income days. During college days and very early marriage years, we spent little ‘discretionary’ - meaning ‘luxury’; we had financial goals to get into a house ASAP (paid off H’s school loans which were low considering he had 2 brothers also in college at the same time and one teacher income for the family of 6), bought needed furnishings along the way (we lived on one income, had one paid for car between us, the other income would buy the couch, the coffee table, build up first house down payment). We still have the $200 oak coffee table 
There are several ways to simplify things so that you identify discretionary purchasing and trim back unnecessary expenses to start saving for retirement. One needs to see some ‘traction’ so that being frugal on spending - that you see some progress.
I originally thought we would downsize our home here to get cash out, but I don’t think we will sell here until we want to relocate. I also was feeling a bit ‘bad’ about potentially not getting the money out of the house. However rethought things - if we had been renting a home (avg maybe $1500, which is low-balling) for our 22 years that we have been in our home, that is $18,000/year or $396,000 and would have nothing to show for it. Our home is very energy efficient and is in a good neighborhood. Will have some sprucing up to sell, but not feeling bad about the money tied up in the house all these years.
Sunday’s ‘Parade’ had a column article “Money Saving too much or too little”. Had a target chart. At age 40, savings should be seven times your income, and graduated up to age 65 with savings at 12 times your income; that is assuming retiring at age 65 needing 75% of pre-retirement income, and that Social Security income will cover about a third of your expenditures. Everybody agrees that over-saving beats under-saving (unless your squeezing nickels when you don’t need to, or stress over money when you don’t need to).
Most people on this thread have done a great job raising their kids (including no ‘addictions’ in teen years, which are so draining to a family in so many ways), and even if a late start on retirement saving, just getting started and getting intentional is a big help. Protecting one’s health is something that doesn’t cost a lot to do, but it does require exercise and watching the diet. Having the right kind of insurance policies in place.
I have three different Dave Ramsey books that all have Financial Mgmt Forms. Once one goes through the planning process the first time, it says you do two work sheets once a month which takes about 30 minutes, and one worksheet that is quarterly. Maybe updating once a year to review/adjust. It says should be able to manage your finances in 30 minutes per month (plus what it takes to write checks and balance your checkbook). If you cannot identify where your money is going, how are you going to control it? If you leave stuff out, it gives you an excuse to quit.
For some, there are extra expenses with students away at college (if the student is not handling their college fund themselves). I keep a running total of expenses so that I then transfer $$ out of their college fund investment (where I am custodian). My kids should be debt free with gaining their degree, with hopefully some money left in their account. They know they are fortunate. I had inheritance from my parents that died too young (63 and 77); those funds came in over several years and helped us during my cancer years and H flat income with additional expenses.
Always things to do when it comes to having ‘everything in order’.
Since we are probably 7 years away from retiring, we did pay taxes on converting IRA to Roth IRA. 2015 will convert the last of it - this helps close out an account that had annual fees. I estimated 28% on our taxes (we are not bumping into the next tax rate) - have to work on 2014 taxes yet, but sent in an estimate. Having the Roth money gives flexibility when you want to stay below a certain income level in retirement years - so if you need a few thousand, you have a place to get it. Plan to keep the Roth money building up those tax free dollars.
