You can't accomplish anything worthwhile if you inhibit yourself. If life teaches you nothing else, know this for sure: When you get the chance, go for it.
Peace, in the sense of the absence of war, is of little value to someone who is dying of hunger or cold. It will not remove the pain of torture inflicted on a prisoner of conscience. It does not comfort those who have lost their loved ones in floods caused by senseless deforestation in a neighboring country. Peace can only last where human rights are respected, where the people are fed, and where individuals and nations are free.
The appearance of things changes according to the emotions; and thus we see magic and beauty in them, while the magic and beauty are really in ourselves.
