Why people get stuck

"Growth means change and change involves risks, stepping from the known to unknown" - George Shinn

People get stuck because they fear changes. People are always happy in their own comfort zone. Changes can make them get out of their comfort zone. Changes can make them do things from beginning . Changes can bring uncertainty in their life. But changes are important for your growth. Its law of nature that things change. Those who fear change and sit in their comfor zone will never achieve more in life. Just my two cents thought on this quote I found in book "Believe it to achieve it", by Brian Tracy.
