If I could get rid of one of my habits, what would it be?

2012:
Getting distracted from the task on hand. I recognize that I have a major issue with it and I am consciously trying to focus more, but it's just hard most of the time. However, lately, I'm doing much better at avoiding the distractions and getting things done!

Today, I cleaned up over 10,000 orphan, duplicate items from iTune!!!!

2013:
Getting sidetracked! Still need to work on that one!

2018:
Other than being distracted, I would love to stop holding on to the grudges.
