Is there a secret in succeeding?
Yes, its so secret though that noone can tell it.
Success can be measured in different ways, just by graduating college you will have already have one form of success in your life.
I can not tell you the path to take, each person has to find that on their own. Start now though and network yourself, most colleges have guidance/employment counselors, make use of them. Use America's Job Bank,

THE RESUME If you worked while in college use it regardless of what it was, this shows willingness to work and study. State education but dont dwell on it, they know you have the degree, you need to show what else you have done. ABOVE all keep the resume short, concise and informative.
I know many will probably disagree with this statement and I do not mean anything deragatory, its just a personal observation. Since your name here is PLCgirl, I will assume you are female. This will mean you will have to assert yourself more. You have gone into a field that by its nature is not a fulltime desk job, can be very dirty, require lots of travel and is not overly populated with women. I have met a couple of women with Electrical Engineering degrees but they both went into Sales. Please do not take this wrong, I am not saying anything deragatory just stating that you may have to assert yourself a little more to get someone to pay attention.
Dont forget that you dont necessarily have to go into manufacturing, their is Research & Development, Sales, Education (Training) etc,.. Talk to or submit resume's to suppliers like local Electrical supply companies, ...look at ANY company that may need an entry level engineer and dont expect to like your first job, its rare that happens. The first job is to get experience.
I wish you luck and to make all I just said short...To get that job will require you to work for it. As I said you have already had success, you will have more.
