#2I can’t accurately estimate non-trivial software. I’ve never met anybody who can accurately estimate non-trivial software. I’ve never seen anybody claim to be able to accurately estimate non-trivial software. Yet for some reason people still insist that estimating non-trivial software is not only possible, but trivial.

It's always maddening to get into debates about this stuff with project managers who believe this nonsense. I know the Fibonacci point scale is supposed to address this by giving PMs something, but I've only ever seen it turn into time-estimates-by-proxy.
These days, I only ever give estimates in terms of time scale. A task will take "hours", "days", "weeks", or "months". As long as it's within my power, my team will only ever estimate on that scale.

This 100% this. I run my teams via "Kanban" (I don't know how kanban it actually is, but that's what I call it).
The only question I ask around prioritization is "Is it worth doing?" If the answer is yes, I ask the stakeholder if they care how long it takes. If they do, I ask for a range and give a best estimate if it's achievable. If the answer is no, I ask why they care how long it takes if it's the most important thing to do.
My engineers know that they're expected to do that one project to completion, and we loop in other stakeholders (marketing, sales, QA, etc) progressively as we approach completion. Admittedly I work at a company of 20, but it works remarkably well, despite the absence of a "schedule"

The trick is to break it down until it’s all trivial. That process takes time itself, but you can estimate that much more easily. I’ve recently found I end up giving an estimate of, say, 2 days to get a solid estimate, and then come away from that with 2-5 weeks of tasks that are no more than a day each. Estimates of a day are pretty accurate (for me).
Another approach I had some success with was estimating the 80% likelihood case, I.e. I’m 80% sure I can finish this in the time I’m estimating. Less accurate, but much more predictably on schedule, which is more useful for many stakeholders.
A last one is giving rough estimates and being clear about how rough they are and how much time it will take to get more confidence. I was handed a 50 page PDF of API docs for a service and asked what the estimate was for integration. After 15 minutes I said “1-4 weeks”, if you want more accuracy then I’ll need a few days. The answer was “no problem, we wouldn’t consider it unless it was These examples are all on the weeks to low number of months scale, but the same applies further up. Having a good understanding of the codebase and domain are very useful.
Estimating isn’t easy, but treat it like any skill, it can be improved. It requires some flexibility from product managers, but open communication goes a really long way and results in better decisions overall, less wasted effort.

I do pretty well at it. My method is to identify all the components of a system and individually assign how many days I think I could do it in if I was really motivated. Then multiply by about 2-3 depending on your experience implementing previously similar modules. Then multiply by 2. I usually end up with a conservative time estimate where some things take longer and some shorter but overall it generally works. On this project that approach would have been... i can do it 3 weeks, give myself 6, and double it = 12. People love it when you come in at or under estimated time and really don't like it when you are late. Give yourself a buffer.

#9Im 18 months into a project i thought would take 6. Why? Co founder bailed and i took some shortcuts early on to try and secure some clients that fell through, those shortcuts led to a substantial rewrite.

OP here - it's just (somehow, repeatedly) surprising the magnitude to which you can be wrong, even when it's just you and there's no pressure from anyone else to get it done quickly and it's really just an honest guess.
I see this over and over again with people I know bootstrapping projects - the over optimism I think is just part of being a builder. Sometimes in startup circles there seems to be this meme of how you should 'throw together a prototype of the tech in a week' being the standard way to get going with an idea. In practice though, seems so impossible that you could get anything even useful shaped built in that amount of time. For me when I get down to work on something, even just plumbing together the vague structure of an app takes longer than a week full time.
