If I Knew Then Advice on careers, finance, and life from Harvard Business School's Class of 1963

Pursue your own interests, and not the wishes or desires of someone else. Find a mentor to provide advice and guidance along your career path. Be prepared to relocate geographically to gain a more complete knowledge of your company, and to experience other lifestyles and cultures.

Leading by example is by far the most important characteristic of a good leader. Being decisive, firm but fair, and setting well defined goals for yourself and others are also very important.
