It shouldn't be so hard to psych yourself up over something very very cool, even if it's unlikely to happen. Like Omg, what if I was picked to be an astronaut going to colonize Mars, or what if I won the lottery, all the cool things I could buy and do, or what if [insert your fantasy here]. We all do this, it's called day dreaming. And the possibility of you being asleep and dreaming at this very moment is higher than winning the lottery. I don't want this to come out rude, but "just do it".

During day, pause what you doing and ask yourself a question "Wow, am I dreaming?" that jolts your attention and makes you stop doing whatever you doing. For a moment, entertain the idea, that you are sure this is a dream or false awakening and feel the excitement in the pit of your stomach. Just pretend, that you have had a lucid dream before that was indistinguishable from waking reality, so this moment could also be a dream and you don't know for sure until you RC. Really consider the answer. Don't just automatically answer "Of course I'm not".
