True, always the last 10% consume as much effort as the 90%

View on HN

I've always phrased it tongue-in-cheek:

"The first 90% of the work takes 90% of the time. The last 10% of the work takes the other 90% of the time.

That reminds me of the Pareto Principle (20/80):

http://en.wikipedia.org/wiki/Pareto_principle

I've found it to apply to many things in life.

Edit: why would this be downvoted?

Because someone tried to upvote you on a smartphone, and Hacker News has a stubbornly non-mobile friendly design, with no undo.

Lol. Yep. I accidentally do that every so often, and I always feel bad about it.

Does anyone know what the rationale for not allowing users to undo votes is? I'd be happy even if it were only accessible for the first few minutes after the initial action...

There have been several times where I've accidentally upvoted low-quality (sometimes malicious) posts, and I never feel good about it.

Individual downvotes are sometimes errors and are usually quickly corrected.

Same math applies to software and book-writing

    Mental: 64.29%
    Physical: 35.71%

Writing software is 60% understanding the problem, 25% understanding the tools, 20% understainding requirements, and -5% hacking the solution to make it fit requirements.
