多様な職務経験を組み合わせて独自の専門性を築くこと

In the past, a career generally meant climbing the ladder within a single company. However, as lifetime employment is no longer the norm and work styles diversify, the need for individuals to autonomously build their careers is increasing. In this context, the idea of 'career portfolio-ization'—creating one's own strengths by combining various jobs and experiences—is gaining attention. As a result, individuals are now required to have the ability to navigate society with their own expertise as a weapon, rather than depending on a company.
