From a previous discussion:

It is important to not look at all of things that you can't do that you could do before. A better approach is taking one thing that you want to do a finding a way to do it. Don't start with something difficult, but pick something you haven't been able to do for a while. If you don't succeed first keep trying learning from the first time. Be mindful of your pain. Don't let it get so bad that you can't move the next day or couple days, but don't let it stop you from achieving your goal. When you accomplish your goal you should feel great. Don't reflect on all the other things you can't do ( you will get to them eventually). Enjoy the moment. Then you can move onto the next task or work to continue to refine the process for the task you achieved. Every time you accomplish something always take the time to look at the different tasks that you can do now and see the positive. It will help to give you the drive to continue to improve.
