Well, I think she might be better of with Mx274 as it’s really harmonizing, both for her and those around her, and people do become really nice…and then maybe less likely to try and take advantge of her not being able to say no? If she’s overwhelmed with work it’s also great for stress.
Mx300 is a really good one, but if you use to much or if she’s sensitive to it (like I am) she might get a little bitchy with it. It is great for boosting the work related confidence though, and she might do well with that one as well if she just needs to be able to say no abit more. Mx300 wont help her with stress and feeling overwhelmed though.
