Think of the work you have to do as a game. If you are having fun with your work it will come naturally. It feels like a weird timeskip because you lose yourself in a state of focus and "enlightment"many people call "being in the zone".
Listening to music that fits the mood of the scene you are going to make helps too.
It also helps me to see the comments in my comic. Seing my readers having fun makes me want to share more of my story and makes me excited to show all i have planned (and to plan more).
