You do not often fully switch off from work, even when you are not there, but you need to relax and you should do so today.
It may be a long time since you had a proper break and it's high time you took your work hat off and relaxed. You may think you have time away from your work, but you usually still have your head in your projects and tasks. Today leave all that behind and forget about it. Plan a trip away or just take some time to fully switch off and wind down. You deserve a rest.
