Please don't learn to speak a second language. It can be hard and even with tools like Rosetta stone, Berlitz et al, many people just don't have the passion to learn these sort of things.

Or... You could try and see if you like it. Awesome tools exist nowadays to enable us to try many different disciplines. Many of these are over-simplified and will only get you so far, but maybe you get a taste for a new hobby or a second career.

I get what the article is trying to say, in places. However, I really believe in the try it and fail approach. You can discover talents and passions you never knew you had. That is unless you don't try to learn...

On the other hand, they say ignorance is bliss.
