When we have made the decision to take out debt to be able to meet what we need, of course we are obliged to pay it off, for some people who run businesses they have to take out loans from banks for capital in the business they have run and also as a motivation for them to work working hard to make the business run well so that they can pay off the loans they have taken from the bank.
It would be better before we decide to take a loan from the bank, we must first assess ourselves whether we will be able to pay it off and if we think we will be able to pay it then we can take it, don't let it happen that after we take the loan we can't pay it off of course. This will get us into a problem that we should be able to avoid.
