There's no real way, in my opinion, to just force affinity towards a topic. My guess is that you have gotten some questions wrong, or have found some difficult (generally the reasons why I hate some topics) and these have discouraged you. I recommend you do some trial questions on conics, and become familiar with types etc. I think if you get many of those harder ones out, you'll feel quite happy with the topic. Correct me if i'm wrong, by all means..
