I should to write down a few key tasks I plan to work on for the day and number them by priority. And tackle one thing at a time. Repeat daily. The second thing I found helps is washing my hands with soap several times throughout the day. It helps dry up the moisture in my hands. I also keep hand sanitizer in my pocket. 

Third thing is not being afraid to talk about my insecurity. From several interactions I’ve had, I learned that several people actually have similar things happen to them.
