When you are carrying a building on your back and you can feel your legs ready to give out, you start thinking that your life is down the tubes (which it is not) and that you are a failure (which is absolutely not true.)
A setback is a life situation that is not working out right now or has already happened. But it’s really important to understand the difference between a life situation and who you really are.
A great piece of advice was given to me many years ago: “Remember who you are.” That is pretty powerful if you can allow yourself to truly believe it.
