You are automatically promoted. Whom you know doesn't matter, as long as you have done reasonably well. While that is true in school, it stops being true the minute you leave. Scan your extracurricular activities in high school and college. Many successful careers have their roots in extracurricular activities or interests, rather than academic ones.
Extracurricular activities develop talent and specific interests.
Each activity in which you have participated probably has many aspects that can carry over into the world of work. Get to know you professors, counselors, club sponsors and deans. If you've been an active student, these people already know you and are aware of what you might be capable of doing. Ask them for advice about a suitable career, a company where they know someone, graduate school, or emerging career fields. Use the career placement office.
