WOW, Hope for Change, you have some amazing suggestions, a lot of things I do are similar. You should make your own separate thread for this, it's amazing!

Here are some things I do...and I had a list of stuff, but to me this was the most important I wanted to share to you because it is meaningful to me, and it is very much an at-work coping strategy.

Bring a journal specifically for work. I got in trouble sometimes for writing in it at hotel front desk, but often times they turned the other cheek. Mine burned in the fire, but it was really cool. I had a page that had a precious family photo of me and my parents and my brother, and underneath I wrote, "I can do this...they are counting on me!" Whenever I felt sad at work, I turned to that page and just looked at it for a while, and remember why I need to stay at that job no matter how difficult it was. I had a few things that went on in that journal that may be helpful for you:
a) Find a mentor. I found a mentor at front desk and she took me under her wing. If she said something brilliant, and with her everything was brilliant, I wrote it down in the journal. "D's Wise Words". She was full of inspiration and I watched her like a hawk for anything I can take away from her. She taught me how to be a better human being just by the way she treated the guests that passed her by and little tidbits about how she presents herself. There will always be someone you can look up to at work, and if not, look for the worst employee and ask yourself, "What about this guy do I NOT want to be like". Feel free to judge, because if you look at the best employees and the worst employees, it will show you what kind of person you want to be like at work, then make goals to become like them, or not like them.
b) Set goals. I have had many, many goal journals, even goal journals for work. Start off with three daily goals, and then one overall goal you'd like to accomplish this month or this year.
c) Write lists of exactly what you need to do on a typical work day. All the routine stuff, odds and ends, and anything you can do to help out your coworkers or bosses. This way, you come to work knowing exactly what is expected of you, and you will be showing your bosses that you are a good employee when they see you doing things you need to do without being asked. If something is difficult, or specific, write that down. When I was a housekeeper, my first few days I took notes of exactly how a room should be cleaned, the chemicals and what they are used for, etc. I did the same at front desk. I had my own section of "To-Do's" so that I can always stay busy.
d) Dedicate a page in your journal to take pride in your job. Write down the company's slogan and their mission. Write down or keep copies of handouts of good information about the company, even if it's something like a sale going on or an upcoming fundraiser. Sometimes, if you want to excel in the company you gotta think like the company.

There's a lot you can do with a work journal, those are a few suggestions, and it really helped me focus on the job when I really didn't want to be there.
