Some people find Smoky Quartz to be energizing. While I do get energy from quartz in general, I also have found out the hard way that this stone can enable ME to doze off while meditating. So maybe this is one to experiment with when you're NOT about to engage in activity that requires full alertness, lol.
Carnelian is a bright, upbeat stone, so that's one whose energies you might want to bring on board while you're trying to pep up.
And I can vouch that diamonds can really give you a burst of energy, if you tune in to them. This is one stone that does not need to be monster-sized in order to pack a punch. Just make sure that you've got your Tact Circuit booted up and running, because I discovered that when I first tuned in to diamond, suddenly I was a LOT more outspoken than I expected. So if I hadn't been tuned in to being tactful as well, I might have gotten a few people seriously steamed at me. I wouldn't want that.
