Career capital consists of skills and knowledge, connections, credentials, character, and runway. Skills and knowledge reflect what you learn, how useful it is, and how fast you learn. Connections involve the people you meet and work with, potentially leading to collaborations and mentorships. Credentials encompass formal qualifications and achievements that signal value to future collaborators. Character development is crucial, focusing on virtues and the influence of working with individuals of good character. Runway refers to financial stability, indicating how long you can live without income, influencing major career decisions and financial security.
