This document discusses the evolution of careers from Version 1.0 to 4.0. Version 1.0 involved doing any work to survive, while Version 2.0 emerged with large organizations in the late 1800s/early 1900s. Version 3.0 focused more on work-life balance. Version 4.0 involves continuous learning and using one's talents to positively impact others through their work. It also provides tips and prompts for discovering one's purpose, including exploring strengths, values, interests and personality. The key message is to keep growing and knowing yourself as you progress through different phases of your career.
