I am currently doing a PhD but I have imposter syndrome! I feel like I am not 'intelligent' enough. I feel like I am getting to grips somewhat with my field, however when I speak to other academics, they appear a lot more articulate than I am. I sometimes struggle to string together an 'intelligent sentence'. I am now also teaching at the university, which in some ways has increased my confidence, but I also doubt my abilities in the role.
Tonight I have been watching University Challenge, and it has got me thinking, how can I increase my current intellectual levels? And how does one broaden their knowledge. Are there any techniques or tips that anybody has?
