I often think of EA problems and solutions in a very numerical manner.
I think this leads me to disconnect from the more emotional aspect of helping other people which makes the motivation purely rational. This then means that I more or less need to be in a more conscious state to be motivated by EA problems. Daily life is, however, distracting and I find myself doing things that don't align with my conscious goals. I know of the more general ways of keeping distractions out but I don't know of many EA-specific ones. I was therefore wondering how other EAs evoke emotional motivation? (An example of this could be having a picture of children in malaria nets or another empathy-provoking type of picture.)
I just have a very ingrained working routine where I start work at a certain time and stop work at a certain time. If I stop working too early, I feel guilty because I haven't finished my allotted work time yet.
It has some downsides (e.g. it doesn't allow for much flexibility if there is more or less productive work that needs to be done within a particular time period) and might not work for other people, but I think it's been pretty effective for me for my ~3 years of remote, EA work. I haven't ever really felt drained or burnt out. Occasionally I feel kind of down about things not working out as well as I hoped but it doesn't really reduce my productivity.
I realise this answers the title of your question but not the emotional aspect. I don't really feel the need to be emotionally connected to the work if I have a productive routine that keeps me engaged.
