When we realize how limited we are, we lose our sense of pride. Our pride grows when we refuse to acknowledge that we are limited in some ways. Many of us believe and fine tune our minds to accept the theory of positive thinking. Sometimes we make it look like we have the ability in ourselves to do anything. This thought becomes wrong when we do not recognize that it is God that works in us; that we are able to do all things through Christ who strengthens us.
The Unlimited One is the Almighty God. There are many kinds of gods who are limited (some, much more limited than humans. That is why their worshippers sometimes have to help them to fight their enemies. These are the limited gods). Our God is Jehovah El-shaddai. He is not limited in any way. Tell Him about anything that troubles you, He is more than able to fix it for you.
