Writing from Privilege Product Management is about delivering value, whatever that means to your current status.

Check out my new post: "Writing from Privilege".

Don't let the FoMO-driven content win. Keep learning, but ditch the guilt.

What's the most unrealistic piece of PM advice you've seen lately?

I think it was the same guy both times. But I couldn't swear on it. It happened few weeks apart.

And yes, both times could have been accidents. But my gut says he’s doing it on purpose. They’re small things, nothing you can report, nothing that causes real harm, not enough to confront them as he could "hey, I am just clumsy".

But enough to ruin the day of the woman he targets.

Yesterday at Postdamer Platz, the train wasn’t very full. I stood up to leave, a guy rushed ahead of me, and he crashed into a woman sitting across from me. Her legs weren’t stretched out or anything. As I stepped off, I realised he looked like the same guy from Eberswalder.

I looked around and saw a guy coming down exactly where she had been walking. She kept going to the U-Bahn. I stayed there confused, looking at him. He looked back, said something I didn’t catch, and then left.

First time was in Eberswalder. I was walking up the stairs, listening to something, lost in my thoughts. Suddenly the woman in front of me crossed to the other side of the stairs in a really unnatural way, and I heard loud shuffling steps behind her.

I usually bike around #Berlin, but the last two times I used the #BVG, I’m pretty sure I saw the same guy β€œaccidentally” bumping into women. Both times on the U2.
I think it was the same guy, and I think both times were on purpose.
But you could also argue they were accidents.

Avoiding micromanagement Fight micromanagement with transparency and room for discussion

New post, about micromanagement and how I try to avoid it.

Also some anecdotes about storms and farms, and lots of analogies with farms and trees.

Have you been on either side of micromanagement? I’d love to hear your take

Loving the Process Why how you build a product can matter more than what you're building

How you build the product is more motivating than the product itself on the long run.

Check out my new post, where I talk about 1 of first culture shocks I had after leaving academia and joining the product management world. + I address what does it mean to have an statistically significant experiment (the reason I go on the culture shock journey).

Yes, the iban they gave me is Belgian (I live en Germany), and I can transfer everywhere in Europe.

You can open a free account, if you want I have a code and we both get some money.

I don't understand why is YouTube Music censoring @rageagainst.bsky.social asking to click to acknowledge that the song may have references to "suicide or self-harm"

If I have a playlist running, it just stops playing and no control works whatsoever until I click on the disclaimer.
