Well, over the phone is a challenging task. Not impossible, but since there's a lot of things that we cannot show visually to the client, to the potential client, so it makes it more difficult. How do I overcome these challenges? And it requires more time. I have to present myself as a trustworthy person through perseverance, by calling and calling and calling, and establish every time I call, I will establish the next appointment, next phone call time, so I can make sure that we can continue this conversation in the soon future. So, the phone call is challenging, but once I establish this trust, we can move to the in-person visiting, so by then, in my particular case, it's like a done deal. As we move on to the personal level, to the home visiting level, it's almost 99% case close. So, I think to overcome these challenges, how to present myself, and dedicate more time and patience to the phone call.
