From the industry, I switched to academia many years ago.

So, the best way to climb up in academia is by having a PhD. I can say the pay rise is quite sizeable between those with and without a PhD.

Besides that, I also have an interest on doing a research in organisational behaviour.

The Dr title is not my major concern at all. For me, it is not even a reason to do it.

To sum up, my reasons are career development, salary factor, and interest.

When i was in the industry early in my career, I don't have the passion at all. I felt dreaded going to work. Working hours could extend to after midnight as well as Saturdays and Sundays. I don't see the point of doing all those work.

But in the academia, it doesn't mean less work. U still need to read, write, carry out research, prepare notes and slides, prepare exam questions, mark papers, etc. All those work could eat up your time past midnight including Saturdays and Sundays. But the difference is that I like the work involved.
