I have depression.
And just because I have depression does not mean I'm any less lovable, investable, or any -able.
A part of me refuses to die, and this part knows I can turn my pain into something positive for others.
This is my creed, purpose, momentum, gravity, and rope…

Demand is growing faster than churn
@neurosity
I think it’s right to give people the option to cancel, versus forcing them to buy a product outright immediately. I see churn, aka membership cancels, as a form of feedback we can measure.
I saw a customer join the membership…
