In the sentence, "He needs to concentrate more on his career," the word "career" can be understood to mean both "job" and "work life," but it generally refers to a broader and long-term professional journey. It encompasses the various jobs, positions, and roles a person holds throughout their working life rather than just a single job. A career often involves progress, growth, and advancement in a specific field or industry. Therefore, when someone is advised to concentrate more on their career, it typically suggests the need to focus on long-term goals, professional development, and overall work performance, rather than just an immediate job or specific tasks.
