There is an old discipline you can try to gain that much needed, perhaps lifesaving perspective. Get yourself a little notebook and a pen. At the end of each and every day, or at the beginning of the next day, take a few minutes to jot down those things that happened in 24 hours for which you are grateful. Small things do count. On some days, very small things may be all you have. Write them down and treasure them.
Review your log regularly, especially when you feel ground down by life. Your gratitude log can become a wellspring of joy for you, a reminder that being part of this world is a really good thing. That is valuable information to have on a rough day.
Don't imagine you'll remember these little things if you don't take them down. You won't, especially when stressed. Keep that book close at hand. Perhaps you'll even find yourself jotting things down right after they happen as time goes by. Who knows?
This is a discipline that has been around for centuries. It has lasted so long because it works. It's a personal life preserver just for you. Use it well and know that you are blessed.
