Aloha Penny,
Thank you for sharing about your first experience with the course.
A couple things:
What was he purpose for hanging the mirror behind your bed?
Regarding changing the front door (assuming that shifting the mobile home isn't an option),that could potentially be done with a hexagram. You can do that through a consultation with Learning Strategies to check on whether it's possible, and if if so, if it is beneficial.
How prominent are the beams in the ceiling? Do they stick out 1, 2, 3, 4, or more inches? I'd look at the ones that are over places you sleep, or spend a lot of time at - like and office chair.
Much Love, Shawn
