However, if this post leaves you open to the option that you might know more about $THING than a library author... that is probably a very healthy possibility to consider.

(Consider. Some are that grad student who got assigned to write the library because they were too useless to do anything else. Others are David M Gay.)

Beating library implementations is usually very easy since you know your use case perfectly and they don't. You need to be way less competent than them to not be able to do something better when you write a tailor made solution. The main reason not to do it is that it takes time and makes the code harder to get into for new hires.

Indeed! That you should be optimistic about it is the best thing to take away from the post.
