What's an important (in your opinion) skill too many people seem to lack?

My mom said "never learn to sew. You will look at clothes and say 'no way I am buying that, I can make it' and then you won't make it, and you will have nothing to wear".

I did sew costumes for my kids for Halloween, stuff that doesn't have to last, but get what she was saying.

I do, however, cook much better than she did and am not sorry, still like going out to eat. And can make cocktails better than most I'd get at a bar but still find joy in going out for a drink. I think she was right about clothes though, they aren't an experience like going out to dinner.
