I've heard the statistic given, but it still is crazy to me to hear that it takes a person 23 minutes to get back on track after being distracted from a task.
Through classes like this, as well as other personal development books I've read, I've found I need to work on the following:
figuring out what my focus for the day is the night before
setting up routines and building in new habits around existing ones
knowing HOW much my environment affects me and doing everything I can to ensure it is a good one
I know how hard it is for me to get started, so it's important that I start small and that I minimize distractions and protect the time I schedule for myself
if there's a task that can be handled quickly, don't put it off--just get it done
The above are a little vague, only because I don't want to get into super specific things--don't think that'll be as beneficial in case anyone else reads this!
Maybe I should take a page out of Kevin's book and try to structure my days around specific tasks. I like that he works on email on Mondays and tries to keep meetings to Tuesdays. I should be able to set up something similar, figuring out what days to focus on writing scripts, filming, editing, and working on other art.
