Howdy, Folks...
"Help them along by adding soil to your water as you witness root growth coming on."
I thought I could offer more explanation if this tip ever came to the forefront; it was hard to explain it in a few sentences.
"Adding soil" won't mean just a sprinkling of soil to the water but rather turning the water into a thick slurry, more soil than water. Once the roots declare you can use an "extra moist" medium. This lets the water-loving roots keep on keeping on (how's that for an expression from the '70's!? ) and encourages the newer roots to grow adapted to soil. It's the best of both worlds.
Sometimes I start plants in water only then move them to super-damp/moist soil. Other plants I start directly in moist soil and skip the water treatment.
Lastly, don't forget what fun it is to have a glass or jar full of water on your kitchen counter with who-knows-what sprigs in it, rooting happily away. I think all of us enjoy that. Lots of houseplants will easily move from the water glass to a pot of soil, especially in a controlled environment like your house, sun room, atrium, etc.
