What would be the best skill to achieve in college before becoming a civil engineer?

I recommend you learn empathy. Empathy, and high emotional intelligence, is key to a successful career and life. In engineering we can often put "things" before people (or appear to do this.) Engineering at its core is a service profession -- service for people. Do what you can to learn empathy, practice empathy and encourage it in others.

In my opinion the goal but common is to understand the procedures in practice, know how it really works, the basis of lessons learned in college.
For when we arrived at the construction site we came across much more learning and difficulties, always learning from those responsible professionals, not forgetting the theoretical part, because many older workers in the area have no further study and technical, only the experiences of your day -a-day.
In fact we will never know everything, every day is a different learning and we will adding more knowledge.

Hi Cristiano!

The most important skill to learn and master now in your preparation for a career and in your career is networking. This is the face to face interaction and communication with people to gain valuable information and create helpful relationships.

Here are some ways that you can start using networking now to help with your future: 80% of peple who find jobs find them through networking. - talk to your school counselor about participating in coop, intern, shadowing, and volunteer programs that will allow you to become involved in civil engineering - talk to the head of alumni relations at your school to arrange to meet and talk to graduates of your school who are working in civil engineering so that you can see what they are doing, how they got there, and how you feel about that. - talk to reference librarian at your local library to locate professional organizations in your area so that you can go to a meeting and mix and mingle and learn more - these organizations are very welcoming to students who are interested in learning more about their field.

Best of luck! Keep me informed. I would like to follow your progress
