I'm afraid you're not going to learn toughness in a book but rather through tough experiences. If you want to train it (I think it's something you can acquire more easily at childhood) it's up to you to "design" these experiences as tough enough to harden you but not so tough that you will break. Some silly examples that comes to me : - try fasting (if your medical condition allows it) - get the shitiest job you can find and last at least one month then give every $ you gained to the political party you dislike the most - go parachute or bungee jumping, ultra marathons / Iron Man - take only cold showers for a year - quit smoking / drinking / drugs - go take care of terminally hill patients Then when you think you've done it all, have a child and learn what determination is through (at least) the next 30 years ;-) A 5 min inspirational read on people that didn't learn tenacity/grit/determination in a book : http://cluborlov.blogspot.com/2013/04/meet-chechens.html http://cluborlov.blogspot.com/2013/04/meet-chechens.html
