What do you think? Should we study/work abroad for a year or so in order to develop ourselves?

Study abroad is always good thing to do. Not just experience on academic study but also culture development. Mind get expose to different things more than your own environment. Go for it!

It's probably a "must". The question now turns to be: "When is the proper time?". It's certainly not about the age.

.it's never too late to study .it's really up to you to plan your schedule .you can work and save up or if you have financial assistants then why not now :)

I'm aware that there is a difference of each one. I would like to get you share how it happened to you yourselves. :) Thanks!

.i was lucky to have financial supports from my parents so i went to high school and university in Australia .i didn't plan for this actually since i was doing secondary school in HCM .just like my fellows back at that time, we were too young and naive to think about what we would like to do/become in the next 10 years! .anyway, since my sister (two years older than me) already went ahead so my parents sent me out too after i finished grade 9 .and now after graduating university, i came back and started helping my dad leading his company

.well, like Duong Mai and Chris Dang Tran have shared their experiences, there is a couple of good things that life will teach you once you stay overseas for a period of time .first of all, you learn how to be indepedent .second, you will be able to expose to many different things like cultures, educations, workplaces, and living environments

.again, you should but you don't really have to
