My solution for this was not to "look forward to the next big project", as my thinking was, but instead I looked back on my life, what were some of my best memories related to work. (there are online courses to illicit this answer, I went through Simon Sineks 'Start With Why', though you might know it anyway). So, I picked my best memories, and they were animation related. I knew that when it came to the 'switch horses' temptation, I would be able to say, "every project gets to this stage, so why would I switch to my 2nd favorite thing, because surely that would be even harder at this phase. Sure this phase is hard, but doing my favorite thing means this is the easiest version of this phase". It's kept me going.
