Since you did not include any of the "following decisions" that you mentioned, I will just give an example.
So, in life, we have times that we have to make hard decisions based off of rough situations or issues. Right? Therefore in that case, I will give an example regarding that.
Just say that you have to pay an expensive bill, right? But your amount of money is short at the moment. And not only that, you are getting CRITICALLY short on food, and you have to get enough food to make sure that you food supply is high enough to feed yourself and your family. But if you spend money to get enough food, you wont have any money left to pay your bill. However, the bill that you have to pay is expensive. So if you pay your bill, you won't be able to buy enough food to feed yourself and your family. So what one do you choose? Do you know what I mean? Critical thinking is kind of like making rational thinking.
