I purchased the STRENGTH key for myself and for my girlfriend. She was going through a divorce and I was going through a very difficult relationship that I was not able to share with anyone. This relationship continued for almost a year. My career and my family life require me to have my "game face" on 24/7. I needed some help. I will say the most helpful part was when I passed my key along to my friend ( not the divorcee, but another one). She needed it way more than I did. When I gave my key, I felt like I was letting go of my problems, if that makes sense. I hope she realizes the importance of passing it along.
