Learning Choshen Mishpat properly can easily take a decade, and until one does you won’t even necessarily know what sheilos you should be asking.
A shochet once approached the Chofetz Chaim that he wanted to leave shechita and go into business because he was afraid of the responsibility of feeding the city treifos and neveilos. The Chofetz Chaim answered him that there are so many more issurim one is responsible for in business on a daily basis.
This doesn’t mean people shouldn’t work, just appreciate the responsibility involved.
