Of course having other people take some of the workload from you is a great idea... but not everyone can afford that, or has even the free resources at their disposal.
And there are all the answer you can read in the myriad of books available: take time for & care of you/get help where you can/ask for support/ don't take on unnecessary things/prioritize/be organized but flexible/breathe/be realistic but challenge yourself too. The list goes on.
And these are ALL good tools. I'm not saying otherwise. We all need tools in our arsenal. But I think you already hit the nail on the head: take it day by day.
I believe you try your best, and try & remember that sometimes your best is better than other times, and that sometimes your best even sucks. If you're doing your best than that's all you can ask. Like I said, sometimes your best sucks, but if could do any better you would.
I would tell people that there's no one right way to balance your life. If there were, there'd be one book & we'd all buy it. Life just doesn't work like that. There's no magic formula, that if done correctly, is going to make you say, "ah, now I have achieved balance. It will stay this way. Now I can work on something else." Life is a moving target... no, not that, cuz that implies there's some end goal to be reached. More like a journey... or whichever of the endless metaphors or similes you prefer.
Learn the tools, ask the questions, & use whatever works best for you. And just take it day by day.
Anyway, that's what I'd say, if I had to lead a seminar. Thanks for letting me blather on. Now I'd better do a little balancing, and get back to work. :-)
Good luck!
