How do I balance engineering and social life?

Thank you for your question and I am thrilled that you are interested in studying electrical engineering. It is a broad field that is ever-changing and exciting. It is true that engineering is a rigorous discipline and the workload can be challenging and time consuming. Balancing school work and social life is a life-long skill that you will have to master. Engineering is not just about technical knowledge but skills like time management, prioritization, decision-making. Non-engineering fields can be just as tough. Studying literature, sociology, anthropology, law, requires a lot of reading and thorough analysis. Business, accounting and marketing involve a lot of research, group work, presentations, applying for internships. So my first advice is not to be afraid because mastering any subject (including dance) requires a lot of time and effort.

To address the second part, there will be plenty of opportunities for you to participate in other extracurricular activities and social life in school and beyond school. If you confine the scope of acquiring life experiences within the four years of college, your time will seem very short and limited. Learning and acquiring life experiences are lifelong activities and you have multiple decades to do so, while certain things are only available through college experience.

In college, I was involved in cultural dance performances and also took several gen-ed classes on music and sports that I was interested in. I also took several years of foreign language studies. I was able to incorporate my interest in art & design in my final year engineering project. I made an LED lit panel that shifts colors based off of motion and perception of colors on the other side of the panel. Looking back, I didn't have an exciting social life in college, but I had fun with friends, worked part time, and volunteered. 

After college, I started my career as a young engineer and had a LOT of fun and social life. Work is less stressful than college (work is as stressful as you make it), I made decent money to support hobbies like traveling, dancing, taking acting lessons, scuba diving, motorcycling etc. 

The world is a lot bigger than college and you will discover more things to learn and other things you may be passionate about. When one thing takes the front seat, other things may take the back seat for a while. You just have to be aware, set priorities and focus. Don't be overwhelmed trying to do everything. The lesson is that you can have everything you want, but maybe not all the time, and not all at the same time. Best of luck!
