Generating emotion of focus


My planned emotion for today was focus, thought I applied it I think I failed on prioritizing. I finished a report and sent it out for review and then within an hour I got an email to do few edits, I had not budgeted the time for this and I also realized that I had to research on the topic before I could make any edits. This almost took my entire day and ended up working late too. I feel very exhausted and bad that I couldn’t take control of my day. Is there something I could have done here differently to stay on track to my committed emotions?
