We're drawn to articles with lists such as this one out of fascination with the creativity of the writer.
Still, this list is better than many, and we agree with (and generally follow) most of the recommendations.
There are a few exceptions. We solve the problem of "lining up for hours" to visit the Eiffel Tower by buying tickets in advance that allow us largely to skip the line. That's the voice of experience after taking six grandchildren so far up there, with the seventh hopefully to follow in July.
Those quibbles aside, it's an article worth scanning.
