The ratio in your numbers is the whole post. Cold applications converted at about six percent to a screen for you; warm intros converted at something like seventy-five. Everyone knows this abstractly and nobody reallocates their week accordingly.

Nobody has asked the only question that matters, which is where the 40 minutes goes. Run it with a profiler, or if you cannot, just time the stages by writing timestamps between them. I have seen exactly this job three times and twice the answer was that a single gzip stream was being decompressed on one core at about 100MB/s and no rewrite in any language was going to fix that. The fix in both cases was splitting the input into chunks that could be decompressed in parallel.

DuckDB is worth the same afternoon if your dedupe is expressible in SQL, which a composite key dedupe usually is. read_csv straight to Parquet with no Python in the loop at all.

Almost never. You will visit it for the paid agreements, for push notification setup if you use a third party service, and on the day something is in a weird state and you need to revoke a certificate. Otherwise let the tooling own it, because hand-made profiles and generated ones fighting each other is the classic mess.

And accept some burping when your hand warms the barrel. Manageable but real, especially once it's half empty.

The two-night rule is the best filter I've found for tour itineraries. Everything else in the brochure is written to sound identical.

Nib down overnight and it writes immediately. So it's flow rather than a blockage.

Counting conversations feels unserious until you notice the weeks with none are the weeks the product moved sideways. It is the only leading indicator I have ever trusted at small scale.

Reframing it as buying a model of what can go wrong rather than a language on my CV makes the decision much easier.

Liveable comes much sooner than finished, and I would aim at liveable deliberately. Floor, bed, a power system that charges a phone and runs a fan, a box with a camping stove in it, and you can sleep in it and use it while you build the rest. We did that at about weekend six and the remaining eight months were far more pleasant because the van was already earning its keep.

A very light micromesh pass is the standard home fix for a genuine rough spot, but don't do it while you still think it might be alignment or rotation. You can't put material back.
