Who's studying and working at the same time ?

Students who work and study seem to enjoy the best of everything. They get their education and at the same time are able to keep their jobs and get a paycheck. However, it isn't as easy as it sounds and studying at the same time as working is probably one of the hardest things you'll ever do in life. So what do you thing about this situation ?

Some people are obliged to work to pursue their studies.
So, here, it's not a choice.

Some others, do it, because they can manage between the two.
And, here, it could work, if they got part-time jobs mostly.

And, a very few though, try to be smart asses & do both, but they end up by failing in their studies & being fired from their jobs.
