First of all, you better ask "what for" if you go for PhD degree? or put in in other way, Is this PhD degree the ONLY way help you to achieve the objective you target? On the other hand, do you have any idea how much workload for doing a PhD? As my experience, it is huge and quite painful.
We have no idea about your financial standing which is critical to your decision on whether quit your full time job or not for your PhD degree. You better test yourself on your research capability and also your financial support before you go for it. How to test? You will find the way...
非常感谢楼上各位的帮助!如karleechan所说,读博的期间的压力it is huge and quite painful,而我的科研能力也不是很强,只能说性格中喜欢读书,能坐得下来,坐得住这些适合读博。我的financial position还可以支持我辞职读博,但考虑到机会成本,在职读也许是更好的办法。
Is this PhD degree the ONLY way help you to achieve the objective you target?
如果目标是去一所正规的高校,也许博士学历是最好的证明。
再次感谢各位的帮助!
