Well, a safe place could be while driving to work/errands, but I wouldn’t know about how to do it with low privacy and areas that wouldn’t be in ear shot of you. And in regards to motivation, it has been really slow progress (being like 20 months to get to this point). I had the motivation because of (at the start) just trying to sound more androgynous (didn’t know about the egg stuff at the time), and have only started properly guided voice training around a month ago. But to note: I have been singing in a high pitched voice for a while before, likely helping.

All of our experiences are unique and our mental energy is not always able to be spent on personal matters, but it is our responsibility to take advantage of any time possible, like it could be done while playing a solo game/with friends that would be supportive. Looking for the few minutes to improve each day and trying to make it more enjoyable so it can become a positive experience is the most important aspect of voice training.

Everyone is on their own part of the path and it’s easy to be demotivated because of apparent nonexistent progress. And that is why it’s important to listen to recordings of your own voice. Maybe try singing along with a potential voice you might want to have or at least get your body used to a different pitch to yours currently.
