"Happiness is the meaning and purpose of life, the whole aim and end of human existence."_Aristotle

Between personal happiness and societal contribution, what do you think it's important while choosing a career? Long story short, I think personal happiness is more important, because I want to do what I want to do.
Everyone is different, so everyone have their different opinions about what they want to in the future.
But before that, I think a more fundamental question must be answered:

Why do we study? Why do we work?
We study because we want to be happy in the future.
We work because we want to be happy in the present, in other words, 'right now'. (Or perhaps the future can be an answer too.)
The keyword is 'Happiness'. All the things you are doing right now is because you want to be happy. And we have a hope that what we've studied will become handy someday, like seeking a new friend, doing another homework, and finally, finding a career, like we are talking this moment.
Doing what you want to do as your career will make you feel happiness. For example, I have many dreams about my future career, and one of them is about software(computer science), like programming, web development, app development, etc....
If I go what I want to do, then I can feel a thrill every time I do it. And I would think it is worthwhile too.

Of course, everyone has their different situations. Also, the world has different situations and issues, so even I myself can't know what choice I'll make in the future.
But as I get to think more and more about this prompt, I had a question in my mind: Is personal happiness is the only way to find happiness?
While thinking this my thoughts changed, and I got an answer that I really want to say to you(my real opinion):
I think the most important thing is that you have to seek happiness no matter what situations you have.
I know it will be difficult. But wouldn't it be better to be happy when you have to do it anyway?

Happiness can not only be felt while doing something what you want: Having societal contribution as your career will make others happy! And by that act you will be happy.
For example, I had an octagnosis test last year, and the pastor who was talking to me about my results said that if I have a teaching job(like a teacher in school) in the future, I would do a great job(because of my altruistic personality). Honestly, in my opinion, 'TEACHER' was the number one job that I didn't want to do.
But my thoughts changed after I realized that job can make everyone happy. If I'm a teacher, I can feel it's worthwhile to teach the students, and on the contrary, the students can know how to study.
While that thoughts in my mind, maybe societal contribution is the way to make everyone happy.

You can choose to be happy, no matter what you're doing.
