Maybe there are some people who, by having debt, will be motivated to work harder so that they can pay off the loans they have and this requires them not to be lazy because they have debts that they have to pay, but there are also types of people who will not borrow if they don't really need it and this really depends on a person's personality.
When you choose to borrow money to make an investment, of course this will be very risky if the investment cannot run smoothly and it is important for you to be able to think about it before actually deciding to take out a loan to invest, because when the investment we carry out is not in accordance with our wishes. Of course, this will cause problems for ourselves.
Taking debt for investment is actually good because it allows us to get bigger profits, but this also has to be done with fairly mature calculations or calculations because there will be a lot of/big risks that we will face.
Some people have different personalities, but in my opinion it is not good to be in debt unless it is for things that can provide greater benefits.
