Quote From jouri:
Flakey, how could you possibly advise someone who cannot cope very well with stress to do a Part-Time PhD (i.e. DOUBLE the stress)????
I'd agree with that. It sounds a good idea in theory, but can be horrendous in practice. Pressure to do your job outside of the PhD, pressure from your employer to 'get' the PhD, as well the usual stress that comes with doing a doctorate. Ok if you're already working somewhere and it comes up as an opportunity you can't afford to turn down, but possibly not for everyone
I'd agree with doing a masters first too, you'd be making a more informed decision by then. If you've missed application deadlines for the next intake, you could always work for a while - a stint outside academia might motivate you to get back into it, or alternatively, realise there are more interesting things for you elsewhere. My PhD idea came from my masters, and working for a while between degrees has a lot of benefits such as acquiring different skills and meeting new people, plus the money obviously.
