Happy to encourage, you can do it! I got discouraged at first trying to root in water, but since I've stuck to sticking stems in pots and in the ground, I don't think any have failed. The older, already-woody stems can take so long it seems like they're failing, but invariably, eventually, a new stem pops up from the new roots, always fatter than its' mama stem.
You can probably see some lack of perkiness in my last pic, but that's normal, from cuttings done this way, a little wilting while new roots form, some older leaves lost.
