Ask for a performance evaluation. Be ready to accept criticism. Knowing how you and your work efforts are perceived is the first step in learning how to better your performance and increase job security. Always ask how you can improve. Eagerness to learn is what companies want.
Indifference is a red flag indicating a potentially unproductive worker.
Don't expect special treatment. Do not expect concessions because you are young or because this is your first job. You applied for it, you want the rewards, and you do the work. Be on time. Disciplined time keeping is one of the best indicators of a conscientious and responsible employee.
