Risk takers have more chances to win compared to doubtful people.
Maybe that is why there are so many gamblers who regret betting because they took too much risk
(so I disagree with you ins simple words if you don't understand the statement).
Taking risk is good but knowing your limits is important, I mean yeah you must take risk to get rich but that is how gamblers think traders would always make favorable trades which not always mean taking risks.
A businessman could hardly be a teacher, crypto investors will also be hardly a teacher as well
But, a teacher would make sustainable profits while a businessman will make profits and also suffer losses to maybe such an extent that they have to quit their life at the end, I am sorry but I have seen a lot of cases.
Depends how how much risk and risk appetite you have because if only taking risks was making people rich then the casinos would have shut down and the gamblers would be richest people. Knowing what is profitable is not always related to how much risk you are taking.
