Why are some people ambitious to take on higher positions at work?

I'd say the main reason people aim for higher positions is the practical need for career growth. In Shanghai's competitive job market, staying in the same role for too long can actually limit your opportunities. For example, as a UI designer, I've seen colleagues who moved up to lead roles gain more creative control over projects - they're not just executing designs but shaping the whole user experience. That said, the pressure to climb can be intense here, especially with rising living costs. It's not just about status, but about securing better resources to build a stable life.
