Hello! I'm Mr. Seo, an employee in the 25th year of a large company:)

I'm in charge of jobs such as an engineer, researcher, and new business development at the company, and I work as a writer, lecturer, and YouTuber externally:) One day I suddenly thought that I wanted to make my name known to the world, and I started a double life through hobbies and finance, and now I'm a creator who writes books and goes to lectures under the nickname Seo Bujang.

What I felt while attending the course was that middle-aged office workers also have a lot of desire to try something different. The days of working to some extent and only waiting for retirement are over. Now that we're in the 100th century, it's time to prepare for retirement. I created this class with the hope that you will fully prepare for life after retirement through a wise double life. A professional double carer is not an employee who neglects company work. I must be a diligent employee who fills my spare time with productive work while creating better work and performance at the company than anyone else. We look forward to seeing you in class, hoping that both your work and personal lives will be filled with rich fruits! ^^
