Honestly, no. That dream of retiring earlier is not for me. I'm really too young for that, my job is fun and also a purpose in life. If that's so important to you, reduce now instead of saving, so you can retire earlier in 20 years
I neither addressed you directly nor meant myself, but the OP ... ;) Retiring 20 years earlier is probably a bit much :D As far as I have followed, the OP and spouse are already working part-time. Alternatively, regular retirement could be more comfortable, although here surely an optimum between present and future would have to be found.
