No he podido resistirme.
"You may ask how is it possible? Well, let-me-tell-you. If you don't fully understand an instrument, don't buy it. If you would not buy for yourself a specific product: don't try to sell it. If you don't know very well your customers, don't lend them any money. If you do all these three things, you will be a better banker, my son."
Thank you, father.
