Hello! Today, I completed a job at the Dongdaemun Dementia Center that paid 480,000 won a day!

Aren't you curious why I was able to earn 480,000 won by redoing the white cement on 12 toilets and sinks in just two hours?

I have captured the honest story of how I, who used to earn 50 million won a year in Yeouido, quit my job, started a cafe, and then jumped into the plumbing business.

Compared to my father-in-law and brother-in-law, who could fix everything in a snap like MacGyver, I was a complete "clumsy hand" who was ridiculed for my lack of dexterity. However, now I am working and recognized for my skills.

I talk about the "business leverage" that is different from a regular salary, and the definite profit premium associated with jobs that others avoid (such as plumbing and drainage). I hope this serves as a small source of motivation for those considering starting a technical business—whether it be tiling, carpentry, or air conditioner cleaning—even if it isn't specifically plumbing!
