Be willing to adapt and take on new challenges. Understand that the gender gap will not lie in your favor for some time so a measure of perserverence is required. My advice to any aspiring engineer is to acquire as much experience in as many different fields/areas as possible before graduating. Even if you love your co-op or internship, branch out and diversify while you have the opportunity. Honestly, you'll be in school for quite some time, but if you're able to swing a co-op it allows you the chance to also double up and get internships over that summer as well which is nice.
