I usually break down every interval into blocks of perceived exertion. It's not something I consciously try to do, but I just find I make mental bookmarks to gauge how hard I'm going and motivate myself to continue.
I used to do lots of two minute intervals, and I'd make a goal of NOT looking at the clock before the first minute. This is usually when things started to get pretty uncomfortable. One minute on - forget about it....sufferfest.
20 minute intervals, I try to keep focused on effort for the first 10 minute before I look at the clock.
SST stuff, which applies in your case. I go out a pretty good clip, but definitely a bit easier than the 20 minute intensity. I'm breathing fairly deep and rhythmically, but I'm telling myself, "This isn't so bad. I could do this forever." Usually between minute 30-40 it's starts to feel a little annoying. If I'm watching TV, it becomes harder to focus on the screen from about 40 minutes on. The discomfort keeps demanding my attention. From about 45 minutes on, time goes REALLY slow. It's not painful the same way as a shorter interval is, but you feel as if you earned it.
The purpose with all of these is to teach yourself to pay attention to your intensity, pace yourself, understand what your body is telling you - all with the goal of finishing each effort, regardless of duration, knowing you gave it your best.
The power meter helps to keep you honest, but it's all based on your best effort.
