I like this idea. I have used the oldest first method but I like the marathon <10 min method you mention. Sometimes when I can't seem to get going, I find the best thing is to just do a slew of tasks and check them off. This momentum gets me going (in most instances). Thanks!
I like this idea, too, of having a "mini-marathon" of 3-10 minute actions to just bang through. Little victories go a long way for me to feeling like I'm accomplishing things/getting things done. Thanks for the suggestion.
