50/50


Hello,
I have been listening to Brooke talk about 50/50 and I have a few questions. is this 50% joy and 50% sadness?
I understand that we can’t experience one without the other and totally get this.
What I’m wondering is I have had times in my life were I have felt terrible like there is no hope, for months and months, so it didn’t feel like 50/50? It felt like 90/10?
How does it work the other way around if we are feeling great for months, should we be anticipating that something really bad will happen (I’m sure that is not what you will suggest but you catch my drift!)

I would love it if you can explain a bit more about this. Thanks!
