Computer Systems Engineering

Hello, my name is Victor. I'm from Mexico City and I'm studying Computer Systems Engineering online. This is a new challenge in my personal life and honestly I'm very excited to achieve this goal. I'd like to ask a few questions to someone who is a software engineer, because I believe that systems engineering is closely linked with the software engineering, and also I think that all women engineers here are very successful.
My questions are:
Could you tell me how to build a successful career?
What skills and competencies must develop a systems engineer to have a successful career?
What is expected of a graduate of this discipline?
What recommendations would you give to be a person successful in this discipline?
And finally, why are systems engineers and software engineers important now?
I hope you have a great time and I hope that you could answer my questions. best wishes.
