Q: Can I clear my own heart wall and count myself as one of the 4 Heart-Wall clients for certification?
A: Yes! You can certainly use yourself not only as one of the 30 clients required for certification, but you can also count yourself as one of the 4 Heart-Wall clients required.
Remember: You must clear the Heart-Walls completely. And remember to ask if there is a hidden Heart-Wall after you release the Heart-Wall. Sometimes there is still a little bit of the wall leftover guarding the heart, it doesn't hurt to ask! And you'll definitely want to get rid of it!
