How do people manage to juggle their work life and maintain a happy social life?

Healthy prioritization - figure out what things for work & family are most important to you. If it's important that you spend more time with your friends or family, you can avoid volunteering to take on extra tasks at work. Sometimes it will be the other way around. Try not to take on more than you know you can handle, or you may end up getting burnt out & then both parts of your life will suffer. It may mean that sometimes one has to fall to the wayside slightly so that other can benefit, but fluctuation is normal.

Setting yourself specific times to do certain things, leave yourself time to do the things that you love.

I shut my work phone off after a certain time of day so I can spend time on myself and my interests. Calls can be forwarded to voicemail to be answered the next day. And when it is possible I take time out during the day to stretch and recharge. I have also changed jobs that have stressed me out too much, in favour of a job that will allow me some free time in my schedule.

There is a time and place for everything, its good that you can schedule a time to work, personal time as well as socialize time. So that you will have a balanced life..

This reminds me of the quote "You work to live, don't live to work!" It's hard and it's definitely something I've struggled with. For me I just had to put my foot down and decide which hours I was willing to/needed to dedicate to work. Sometimes I have to change it or work a little extra but having that rough plan in place makes it easier to make plans to socialise, and keep a happy balance :)

Through balance. Your professional life is as important as your social life. Making one of them more important than the other can only bring frustration. Work, study, but make sure you find some free time to enjoy your social life.

Work-life balance is one of the greatest challenges for me because I work in a helping profession and I'm very sensitive to others' energies and moods. For this reason, even though I thrive through interaction, I have learned that I need to take time to be alone every day. Because I love being around people, as a strong extrovert, I make it a point to plan to have some kind of social outing or gathering at least two times per month. This gives me the social outlet while also reserving my time and energy during the work week so that I can stay rested enough to do good work with the people I serve.

Maintaining a planner and sometimes even planning our every minute of your day helps you stay on task and be productive. When you feel as if planning is becoming redundant then take a few days off to relax. As an athlete, high school student, and a member of various clubs and organizations I take planning very seriously in order to keep up with both my school life and my social life. Another tip is to set realistic goals for yourself. Don't plan to finish an entire essay in one day, instead chunk out bigger projects and schedule breaks in between.
