A challenge

Today was a tough day, maybe even the most stressful in recent days.  The positive is that by the end of the day, I was back at the point where I started the day.  No progress and I lost 8 hours, but at least I didn't go backwards.  In short, my take away message is when things start to go to pot, keep a calm head and keep moving forwards.  One of my personal favorite sayings at home is "there's no problem that can't be solve."  Given my penchant for puzzles and troubleshooting, I guess this shouldn't come as a surprise, but it's a key strategy when studying.  When things go wrong or when others say something can't be done, do not give up (don't blindly try to keep moving forward either); take a moment and then dive into the issue head-first.
