Married, mortgage, three kids and 18 days holiday a year. On the plus side I don't drink, smoke or buy expensive clothes/cars/gadgets. Like some said, I take time around stat days to extend time off and try for both a one week and two week trip with some shorter multi day trips in between. Even a long weekend gives you time for a three day trip. My kids are older now and don't really want to vacation with dad and my wife has been singing competitively for years so she uses her holidays for international competitions. We make it work. During the young years with the kids I did scouting and day trips diving for myself, forgoing extended personal tours for a bit.
I camp for the most part and tour a lot in my own region so travel is basically by van, domestic flight or train. Fairly cheap. I rebuild older bikes and use what I have, upgrading along the way so it's not a big hit to the pocket book. I'm 55 and in 2017 finally bought my first new bike for a whopping $800. (It was a discounted 2016 model). My last little trip cost $120 train and campsites + food... say $150 all in.
If you wanna do it you just do it.
Grant Peterson coined a phrase S24O which means sub 24 hour outing; basically just loading up the bike and going camping overnight somewhere

It's a great place to start.
Alastair Humphreys also talks about Micro Adventures, which is the same concept
