If you think that you are performing at a substandard level in any area of your life, it's very easy to just blow it off! It really is! It's very easy to think of it as another bad day or a series of bad days. It's tempting to think that you're just going to get out from the under, whatever it is that's holding you back and things will go back to normal. 

Unfortunately, your definition of ‘normal’ starts to slide and can you end up settling for less than optimal existence. 

You get used to frustration. It's easy to get accustomed to a lot of disappointments.
