This is nearly all jobs.
This is nearly all jobs.
All unskilled labor jobs.
You're not going to learn welding in 30 days. Nor are you going to learn how to design a bridge. Or program in C++. Or diagnose a patient. Or be a lawyer. Or drive a race car. Etc.
The thing about "unskilled" jobs, everyone seems to look down their noses at, is that they facilite the people doing the lofty jobs of: lawyer, doctor, c++ programmer, etc. Without them getting done for you you couldn't do what you're doing.
Can the brickie work without their "unskilled" laborer? Sure, but good luck getting you house built in a reasonable time.
Neither are jobs like carpenters, roofers, pipelayers, cooks, truck drivers, clerks and many, many others.
There is nothing wrong with honest work - skilled or unskilled.
