Chronicle of a business minded child (1)

Growing up as a child, i was very curious of the business world and this passion of becoming a season entrepreneur was ignited at a very young age of 6 years. I remember i use to love reading my father’s business books and one of my favorite phrases in Robert H Schuller book then in the 80’s was " Tough times never last, but tough people do". I did not understand the significant of that phrase but it stucked to my memory. And you know what? After more than 30 years, that particular phrase has helped me overcome lots of trials both in business and personal life. What is your favorite book and phrase?
