How do you cope with busy, stressful periods?

Time Management, or as some people call it "Self Management"

Busy and stressful are managed by managing pressure through setting priorities on your daily action plan and leave room for interruptions. 

Develop a positive attitude. For a lot of people this is one of the hardest things they will ever do. It's a fact that people with a positive attitude have less health problems, less stress and more luck in life.
