Don t give it all up in the middle of the treatment, even if there s no immediate cure, or even if it seems long or painful. Extended-life is also life. There s always something to do which we have never done before. That' s an excelent time to give the example and show that you can turn around the most difficult moments with optimism and no desperation. Be the example to those around you.
World is very destitute of good examples.
Keep yourself optimist and smiling. Everybody will also smile in return. This optimistical environment is positive and you must be the first one to build it. You ll be the one who will determine how the surrounding environment will be. No one else.
