Age does not define you, but experience can certainly matter in some work situations or positions. In some areas a motivated young person can outperform and in others it will be simply impossible to do the job to its utmost without having gone through the process a number of times before.
The beauty of being young is that you can set aside the time to become experienced in things that will really matter later on. Making the most of the opportunities presented you while building up a rich set of experiences in your field will allow you to have the most success in the long run.
Always appreciate where you are at any time, take the lessons that situation has to offer you and be aware that you are in the process of building the experience that when combined with your natural abilities will make you a highly valued and unique asset.
