Hmm. I don't think my opinions have changed too much.
I would _definitely_ present these ideas differently today; the language we all use to describe problems and solutions has changed quite a bit in the meantime.
And how I _apply_ these tactics and strategies is much less confrontational than when I was in fintech, mostly because I'm older and more patient.
But the essence of the advice in here is still a big part of how I work: having a technical roadmap to match the product roadmap; getting small wins on the path to long-term goals; talking about what you've built and showing it off; taking responsibility for product and design decisions if nobody else is; building a team who will share ownership; diagnosing dysfunction with Vaillant's defense mechanisms; using estimates to pay off technical debt and experiment with new technology and approaches. All of these tactics and strategies are still valuable in my opinion.
