I never look at the glass as half empty or half full. I look to see who is pouring the water and deal with them.
Mark CubanTo retire by the age of 35 was my goal. I wasn't sure how I was going to get there though. I knew I would end up owning my own business someday, so I figured my challenge was to learn as much as anyone about all businesses. I believed that every job I took was really me getting paid to learn about a new industry. I spent as much time as I could, learning and reading everything about business I could get my hands on. I used to go into the library for hours and hours reading business books and magazines.
