I'd like to share a few simple rules for maintaining sanity in the 9-5 workplace.
Don't start the day with coffee.
Once it is 10:30 take your 15 minute break and drink a coffee. It will help you make it to lunch.
DO NOT take lunch at noon. That is too early and makes the day stretch out for too long.
Take lunch between 1-2:30. DO NOT eat lunch at your desk. ESPECIALLY in the summer time. GET out of the office and forget about work and go for a walk.
If you take lunch at 2 and your 15 minute afternoon break you will be back at 3 and then you have two hours before hometime. Perfect.
Bring some snacks – yogurt, apple, carrot sticks, rice crackers, drink lots of water, hard boiled egg, nuts…
