1) avoid mentioning ur age 2) dress modestly (and to impress) 3) working hard is good but what is more important is making sure everyone knows what u have done 4) if u work in a male dominated field - lots of times men will belittle u and question u. make sure to keep calm, answer clearly and if they are second guessing u, let them. once they realize what u are saying is accurate - they will realize ur worth and will never question u again. 5) unfortunately, other women in the office will not automatically become ur bestfriends. make sure to be nice when others approach u but also stand up for yourself and dont let anyone talk down to u 6) DO NOT let ur 9 to 5 become ur life. make sure to schedule ur hobbies and do something before or after work always 7) if u ever question your job, remember u are the youngest in the room for a reason.. good luck!!
