To keep up the energy and team-feeling throughout the day, we really need to make an efford together. No one should feel left behind and everyone is included. For us, we have done this by dressing the same way, make sure everyone always have something to drink (either with or without the fun in it). And, we have played music all night to make most of stay up late to work with the solution and to give all the other team-members still here at 3am to have as much fun as they can! 🙂
