Start by creating a broad list of career options to avoid ruling out great opportunities too early. Prioritize personal fit, impact, job satisfaction, and career capital to rank your options. Identify key uncertainties by asking questions like 'Would I enjoy this job?' and 'Would the pay be sufficient considering my loans?'. Begin resolving uncertainties with cheap tests to gather information efficiently. Develop a ladder of tests to evaluate each option step by step, starting with basic research and gradually progressing to more substantial commitments like internships. Continuously reassess the viability of each option and be willing to move on to investigate other possibilities.
