I can also do this, don't have perfect pitch, was also a cello player, and have a guess.
Instruments have fairly unique timbres at different pitches, and our brain can pattern match that more effectively than pitch itself. So, you can actually "burn in" the correct timbre, which makes it easier to find. Since I was so used to an A reference note for tuning, I got to where I could get pretty close.
Years later, I saw this video, with someone who seems to have brute forced it to approximate perfect pitch using a similar method: https://www.youtube.com/watch?v=oT22zqg0jvE
FWIW: I'm an investor in all of Calm's funds (I think I was one of the earliest investors in Fund 1), and have been quite happy with the funds themselves. They've done great — outperforming my own expectations.
As indie.vc also found, it's just hard to make these styles of funds work on the business side.
I'm an LP in both Calm and the fund, SureSwift, that's suing them, so I suspect I know as much as anyone external. Weirdly, the only information I've been able to glean is from Calm, but I did participate in the events personally that are part of the litigation.
The other fund, SureSwift, had some drama (founding GP left, replaced with a hired CEO who seems entirely competent), and SureSwift shortly after sued Calm and the former GP. I never got a good picture what happened internally, but there certainly was a falling out.
Speaking personally, the lawsuit seems like a giant waste of time and I haven't heard anything that makes me think Calm actually did anything wrong. I've asked, and got very confusing empty responses from SureSwift. I wish I knew more, since I love this space (calm companies, micro PE, etc) and am personally invested on both sides.
I do pottery as a serious hobby (though, people buy my stuff), and was recently talking with a friend about how—for me—it's not really about producing art, but the personal experience of making pieces.
I'm glad people like what I make, but I do it not to say something, and rather to experience something.
I moved to a new town a few years ago, and was worried about forming a new social group. What did it for me: be the instigator. Most people want to improve their social connections, and many have the same sort of "starting problem". Being the one to organize events is a surprisingly easy way to immediately have many people around, and importantly lets you set the terms of the engagement.
The best short, easy resource on what I mean is this book: https://party.pro/book/. The Art of Gathering is another good one if you want to go deeper.
You may be concerned that you don't know many people, so can't easily organize an event where people would come. This is actually solvable (see the book above). The nice thing is that this also lets you risk and experiment with social failure ("what if people don't show?", etc), which in my experience is the cause of a lot of social anxiety.
Been using Reader as my primary reading + save for later app for a few months. It's truly a joy — it's fast, simple, and works really well. There's obviously a cold-start problem where you need to use it for a bit to get most of the value, so I'd encourage anyone here that's interested in a similar app to give it a couple weeks.
