> How we make life better

That's overly ambitious, and the meaning is also completely different. That says that setting deadlines itself improves life, which is not what the article or original title are saying.

> Use your imagination!

My imagination is okay with "should", when the benefits will be spelled out later, which they are in the article.

It's all good, glad it works for you. I found that for me, when I paid attention to the "shoulds" it was a bigger burden than it was worth for not much gain. Thus I learned it's best to filter them out in favor of messaging that is less preachy and more nuanced. It's a tradeoff, as inevitably I'll miss some good ones but overall it seems like a better way to allocate my attention.

Ymmv :)
