Earn and save more (more like: a LOT) early on, then let those saved and promptly invested dollars work for you ie., compound (wouldnt it be dandy: if you make money while you sleep and/or on vacation).
After some serious savings/investing and ensued compounded growth, then you start to realize, those investments of yours start to add wind to your sails (growth in savings and nest egg).
After some more time, your continued savings, and the growth may almost add up to either your or spouses salary. Now, you decide whether to let one spouses make a less-working (or not working) choice! Once you achieve this level of nest egg growth., you will have many choices to make (good/better ones that is).
After some more time of saving, and compounding., you might realize your savings plus nest-egg-growth may overtake your Net pay, and not long after, your gross pay as well !! At that point - you feel like you have two good paying jobs in the household.
Chances are that you may have nest egg approaching/exceeding 25 times your future annual expenses. Many call this FI and or Early Retirement goal. You don't have to make a choice to retire, just knowing you could, is a great stress reliever. I am afraid, you may even develop new motivation and strength to take on additional stress at this point for additional pay !! (and infact feel less stressed doing the work actually
Now, how longer do you want to continue after this point? You tell us !!
Whats the point here: As you progress along these various stages of career, nest-egg-building, the availiability/utility of Money-Vs-Time may experience different quantum changes (my friend, its not exactly a continuum). Beside, life may thow curve balls at you: job sector gone bad, slow/no growth, high-inflation, nagging/serious health issues, helping aging parents/in-laws, divorce, bankruptcy, or death of loved ones among million travesties.
Like you may have already noticed, Time is free (you don't have to earn it, it comes free to every living soul), but Money ain't - you gotta earn it. Strive to earn more, much-more-badly than others., otherwise., somebody else will catch that ship, you be stuck in your own little paradise island., and may never see/experience bigger/better corners of life/world. BTW, your paradise island may be best island in the world for you., be happy so long family fully supports that decision "Now" as well as test-of-future-time ! Also, nobody may have mentioned to you yet, your own personal paradise island may have a big-as Volcano nobody talks about (personal/life tragedies/u-turns) and possible land-mines. So, do have some serious monies/nest-egg built up to handle such evacuation type uncertainties! Besides, there is no Personal FEMA in everybody's life, your nest egg (Army of Dollars) and good relationships may come to rescue/assist!!
