Taking a break or vacation time at scheduled times throughout the year can really make an impact. It can help you realize what's really important, plus it can reduce your stress level significantly. People may comment about being able to notice your newfound stress relieved voice or posture while on vacation or just after taking break. Even when you didn't realize you sounded or looked stressed just before your planned time off.
I personally started scheduling my entire next year's vacation and break time before the year starts several years ago. I allow a week for sick time or unforeseen time off, but then map out the paid company holidays along with planned breaks and vacations at certain times throughout the year to manage my stress level. It has made a huge difference in managing my stress because I now have set times throughout the year to look forward to with either a vacation or just a break with my family or friends. I have found that this is a good thing to do in my life to control any stress that may creep in and give me scheduled times off to be excited about. It's a better way to live and a great way to model the way for those around you.
