First paragraph : Note that he didn't say that. Revealing a previous passive observation versus giving advice is different. He was basically just trying to say "I think I've had the wrong impression of you", but perhaps wanted to let him know just how strong of a negative impression he had. To me it read more like a sort-of public apology for holding a mistaken belief about Zed's character and possibly nudging others to reconsider any similar viewpoints.

Second point: Yup, optional just like most tools, and just like most tools there's always a set specific challenges where it can work wonders compared to the rest of the shed.

Your mileage may vary but I'd be very surprised if you can't think of a single lesson you've remembered better because there was some pain involved, we're supposedly hardwired to better remember those lessons, for obvious life-prolonging reasons.

You'd be surprised how many lessons are quite useless, regardless of their painfulness. Many of the things that happen don't have a systematical meaning that we can adapt our behavior to, but they happen because of chaos. A car accident that teaches you to always look left first (because you looked to the right, and bumped into a car coming from the left) at intersections can be very hurtful, e.g. if people are killed. And you will never-ever again forget to look left first, and never have an accident again due to this very reason, right? But, is that lesson any good? You might never again get into a similar situation, because the reason you looked to the right at that very moment was some dork honking at you. Or even worse, this lesson could lead to another accident because you are neglecting cars coming from the right.

Pain keeps you from touching that oven or from jumping down your balcony, but it's not a suitable tool to drive home a lesson. It holds us back. If you add painful lesson after lesson on top of your "fixed constraints" stack, then you won't be able to freely move after a while.

Nobody would grasp at straws enough to suggest to another man that the pain with a lesson is directly proportional to it's usefulness, that would be terrible, like the fate of the idiot in your analogy that decides the lesson learned is to look left.

So you burn yourself taking a casserole out, do you stop cooking? I'd hope not, you just now have the good sense to pay attention when dealing with hot, dangerous objects. We cherish this feedback, both as people and as entrepreneurs, that's one of the reasons we build MVPs

We could go a bit abstract and talk about pain/discomfort (including emotional) as devices, and I could give you anecdotes of when a former boss took me aside and plainly laid out why I could never hope to get where I wanted if I followed my current vector, but as we're anecdueling where's the fun in that :p

Talk to any gymnast and they'll usually be able to tell, if not show you physical remnants of, all the painful lessons they've learnt along the path of self-improvement. Ask them if they'd be half as good if they hadn't made those painful mistakes. Better yet ask them what makes an awesome gymnast, they'll usually tell you it's more about having "no fear" when going for stuff. Of course that's an oversimplification and discounts the years of training and talent, but there's a realist perspective in there.

Yes there will be painful lessons along the way, such is life. Not to go all ad populum on you but it's a fairly standard cliche that the people who can take the experiences, learn from the setbacks and not let the fear of another fall stop them trying will learn an awful lot faster and deeper than if they shy away from anything potentially upsetting. That fear of being upset by something is a personal issue and may limit what someone can achieve.

I also read it as a public apology.
