If you have the opportunity to learn a certain skill , what would it be?

There are a few different skills that I find interesting and I would like to partake in. I would like to be fluent in different languages such as Spanish or Italian. I think that knowing different languages fluently are very beneficial in this world and would help me to communicate more efficiently. I would also like to learn to become an actress. I am forty years old now but have always had a dream like this. I am a stay at home mother and also a house wife but I still have some goals.
