Warning is what you get when all things are safe. Most times in life, there is not one. If someone’s car hits you from behind, there is not warning for example. When there is one, you should pay attention to it. If you know you have no income but money in the bank, there is a warning every time that balance goes down. If you’re holding out for that big amazing paying job, perhaps you should think about the warning. Something is better than nothing.
One reason we don’t pay attention to warnings so much is because we don’t know the consequences. Obviously if you go into deep space without a space suit you will implode and die. Most things aren’t that obvious. Warnings without knowledge of consequences are useless I think. A flashing red light only bothers us when we have felt the aftermath. How about these people who are always warning everyone, the “Debbie Downers” of the earth.
These people are sometimes helpful but never let them know that or they’ll never shut up. I have a few of these people in my world and they are inconsolable. While the character is larger than life, I think she makes people laugh because everyone has one of these in their circle. Pay attention to your own warnings and don’t give so much advice, don’t be a Debbie Downer.
