The strains vary on the exact position you are in. However, in general the keys to being a good aerospace engineer is to always recognize there is more to learn and to be humble enough to admit you don't know everything. From a knowledge base, aviation is expansive but having a good understanding of how planes fly (i.e. getting a private pilot license) has served me well even though I work in the regulation side of things and my professional background is from the deign and repair side of the industry. Also, be sure to go after the jobs and task that seem the most daunting. Others run away, thus running towards it provides the best opportunity to grow and learn as well as reinforce self confidence. If you mess up, then make sure you learn the most you can about how you messed up and improve yourself for the next opportunity.
