Main principles for the preparation and the start of entrepreneurial activity

Its a Seminar Paper for course Entrepreneurship. Describe how you could use some of the systemic principles, (any) for the preparation and the start of your entrepreneurial activity. It should be written non-formally, based on practical examples and advises of successful entrepreneurs. I dont need any theoretical thesis and study-books quotes. To use this link is mandatory, but you dont need to write about all of advises. Try to systematise it. http://www.lifehack.org/articles/productivity/the-success-secrets-entrepreneurs-you-need-know.html http://www.forbes.com/sites/homaycotte/2015/11/17/the-secret-to-entrepreneurial-success-informed-optimism/#4c568bc37023 https://business.vancouver.wsu.edu/bgmap/secrets-entrepreneurial-success http://www.businessinsider.com/richard-bransons-5-secrets-to-entrepreneurial-success-2010-7
