The here described approach of keeping the same mindset at day which one would like to have at night made a lot of sense to me. So the last few days I practiced self-awareness. I noticed that it is quite difficult to maintain awareness while doing something else, especially while thinking or concentrating on something. This would make sense, because self-awareness is 'being present' and thinking on something is being somewhere else in a way. How did you solve this problem?

Also, self-awareness does somewhat feel like tensing an inner muscle to me. Over the past few days now, an inner tension has build up, which doesn't feel right. Fryingman said that maintaining awareness is not tiresome, but this tension certainly is. I can't help the feeling that I did something wrong here.
