Your twenties are crucial for setting a foundation for long-term career success by focusing on learning, credibility, and relationships rather than quick achievements. Key mistakes to avoid include prioritizing job titles over skill development, staying only in comfort zones, neglecting genuine networking, ignoring the importance of a strong online presence, risking burnout by overworking, fearing criticism instead of seeking feedback, and making random job changes without purpose. Building lasting skills opens more opportunities than inflated positions, while taking on challenges enhances adaptability. Maintaining authentic connections can lead to unexpected career breakthroughs. A well-crafted LinkedIn profile or portfolio demonstrates credibility and attracts opportunities. Protecting health and setting boundaries prevents burnout, which can harm sustained growth. Accepting and acting on feedback fosters professional maturity. Job changes should be strategic, allowing time to make an impact and align with long-term goals. Overall, careers develop step by step through deliberate choices and consistent effort, making the twenties a launchpad for future success. (Updated 26 Aug 2025, 07:12 IST; source: link)
