Missy, complaining is okay as long it doesn't become your lifestyle. We wouldn't be real if we walked around smiling ALL the time. What's not okay is breaking a commitment to yourself. You made the commitment to walk a second time and you did it. Can you make one of the walks out in the sunshine? Treadmills are great, but you can't beat fresh air and sunshine.
MJ, What did I do yesterday I need to change? As usual, too much time on the computer. As usual, I have overcommitted myself. There are only so many hours in a day and I want to do so much (sewing, nothing strenuous, though my house and garden need me.) Change?? Staighten the sewing area and get to work!!!
