Downsize a little? Fewer of everything will (in theory) give you more time to do other things, makes management less of a chore and more of a pleasure, and not so much for other people to do when you are away. And you still get to enjoy the lifestyle. Don't give it up just yet, I think you would regret it. 60 is still young 
My experience is that, when you're talking small numbers to start with, fewer of everything is not as much less work as you think it will be. It's the number of
species more than the number of feet... There are many jobs you have to do whether you have 4 sheep or 40, 2 cows or 20, and so on. Of course things like shearing are less work with fewer sheep, but the "big jobs" days are relatively few and far between. Most days it's the routine jobs, and a lot of that is per species, per field, etc.
Yes, stopping breeding completely of course reduces the work enormously, but lambing 6 is actually disproportionately tiring (and ridiculously tying), unending checks to see mostly nothing happening! lol. I'd much rather be lambing 60... :/
So my 2p-worth is (1) consider stopping breeding, milking, other activities that are or cause work
completely, along with (2) consider reducing the number of species and different types of management.
For others in the same boat, there are also issues such as the amount of intervention your chosen breed requires... I now use only a (polled) Shetland tup and if I had no other drivers, would probably just have pure Shetland sheep, selected for good feet, natural fly strike resistance, hands free lambings, hands free mothering from the very first lamb, etc etc. We have Northern Dairy Shorthorn x Jersey cows, who are thrifty and hardy, nothing like as productive as pure Jerseys but therefore much easier to care for. (Although one is too good a doer, so we are having to manage her intake to keep the weight off her...) We buy in weaners each spring, no longer breed our own pigs, and so on.
Of course then you have to think how to manage the same number of acres with fewer mouths, and those headaches don't reduce... :/
Best of luck, and let us know what you decide and how you get on!
