What needs to be determined to work hard

entrepreneurs need to have entrepreneurial thinking, entrepreneurship also need? I will have faith and confidence of success, to try some may not have what achievement, like a boy on a beautiful girl said: "Hey, girls, we try to get married, can not leave", and ask for a girl to try? The process of entrepreneurship can be summed up, if you choose to venture, No, No…… My son said, "there’s no door".
