relaxing for a little moment would certainly do you good, but if you dont have a choice, there cant really anything be done about it..
if its little things we are talking about, talking with other ppl keeps me busy as well. i think about what to tell the other person.. kind of like this conversation here. its nice and you pass some time~
not really grand scaled and not really anything much to think about, though :3
then did you try writing a new story? i actually cant get anything done. thats why i leave things half finished and start something new. sometimes i finish those unfinished drawings..
thats bad, though and you shouldnt really do the same, but it should be fine, if you dont start too many new stories.
maybe just writing about things that come to mind or something diary like xD
you could write a story about yourself.. this would keep your mind busy, when you dont know how to continue your actual story i guess..
