It's been a tough day at work. I feel like I'm banging my head against brick walls all over the place, and taking at least one step backwards for every tiny step forwards.
I'm fortunate that my employer supports work/life balance. I've done as much as I can for one day and need to get home, and that's OK and understood. Unless something major happens, I can leave it all behind at the end of the day.
Sure, all the same issues will be lying in wait to do battle again tomorrow. But meanwhile, I can come home to a loving embrace, a crackling log fire, and a cold beer.
