No, it is very important to be yourself, do not change anything about yourself just to impress others. If someone does want to be impress and urges you to do it, do not, not if you do not want to change yourself or to do something your not comfortable with.
Ex: Say your on a tv show, like X factor or America’s got talent. You would need to impress the judges to get the win or golden buzzers.
Ex#2: Say a “friend” said, ”i wont be your friend unless you impress me!” that is something that you should not do. do not change yourself just to impress your friends, or someone else.
