You are being stubborn today because someone has rubbed you the wrong way and not as a result of your response to them really being justified. It doesn't matter to you what the reasoning is behind the action on your part. Instead of changing your behavior, go with the feeling until it doesn't suit your needs anymore. It is a better learning experience to stand firm rather than cave because it is not appropriate according to what others may think.
Capricorn is carefully ambitious and will usually rise to the top of their field. They are incredibly humorous even though they may come across in a less than positive manner.

Capricorn will learn to move slowly but surely upwards to obtain their goals. Capricorn are disciplined and will acquire the confidence they need as they get older.
