Get Everything Done

I notice resistance when I switch between the 2, Somehow if I am doing x then doing y its easier to do z, rather than doing x desking a doing y desking b etc. So what I am going to trial this week is my new "Do vs Desk Designator": an orange circle, if truth be told ! on the lhs or rhs. This applies to the one-off task list in DIT so might not be of use if you are using a different system. Does anyone else think this might be useful of can you think of a better way

Desk tasks are anything I do at my desk. PC jobs, email, cards.
Doing jobs are nipping out for something, cooking, i,e more menial. Clearing a cupboard, hanging the washing anything like that
I find it easier to do one "desking" job after another, or one "doing" task after another
but switching from tax return to weeding to emailing a friend to putting a shelf up makes no sense at all, at least to me.
I need a marker so when I do SS I can see at a glance and if I am on a roll physically I keep going with that or on a roll at my desk I can keep going with that. placing a diffferent marker at the side of the task has helped this - I will keep going with that for a while and see how i get on.

I’d be tempted to list them separately in the first place. Much easier to distinguish for the purposes of batch processing.
