I suggest you turn off the computer, shower and get dressed and go out for a walk. Enjoy being outdoors, say hello to others and stop for a cup of coffee or tea or soda and relax. Bring a pad (or a piece of paper) and a pen with you.

Now that you are out of your home environment, take out that pad / paper and pen. See what other people are doing. Write down some realistic small goals for yourself that are easy and 1 or 2 more involved ones. Break the more involved goals down into small steps that you can work on daily.
