Take every day as it comes

So today hasn't bin the best of days. Finally got called into the office about a promotion that I've bin waiting to hear back from for 2weeks. Apparently 4 have applied, he was asking lots of questions an answered them to the best of my ability...but why is it when your in the car you suddenly think of a 1000 better answers!! All I can say is I work my skin to the bone, I do double shifts everyday nearly, I travel pretty much 24/7 an always help so if I don't get it....oh well another opportunity will arise
