Constant motivation

Brooke teaches of how it is important that we fuel our results with positive emotions. I want my work to be propelled by excitement, pride, creativity. I am committed to feel like that because I truly think my work is great, bu then right in the day I am working and I see myself I am not having these feelings not being excited and I am buffering here and there going to the internet. How do I shift this in the very same moment?
