Personally, I think that, for example, one can put a little effort into handwriting and improve it; however, not everyone has a vocation for the art of painting with watercolors.

but why spend the time on cursive as opposed to, say, watercolor painting.

Kids should learn cursive

I have my doubts about the subject, really in current times we write more on the computer or cell phone, than we write by hand... but the art of writing cursive really is beautiful, unfortunately personally I am terrible at writing, my handwriting is horrible.

In fact, with 32 years of having one of my signatures, it is never the same as the other.
