I enjoyed the article and didn't take it as preaching. Motivation to keep looking for a solution/better solution - yes, but not preaching. However, there does exist the possibility that there is no current solution. That doesn't mean we should give up or stop, but it may be worth saying "I am not able to do this with the tools/knowledge available to me right now" at some point. At that point, start looking for alternatives to the ways available - maybe a "good enough" solution. My first instinct isn't to say "no", but I'm definitely open to the possibility that that might be the answer and we might need to come at the problem/solution a completely different way.
