Be happy when you find that doctrines you have learned and analysed are being tested by real events. If you've succeeded in removing or reducing the tendency to be mean and critical, or thoughtless, or foul-mouthed, or careless, or nonchalant; if old interests no longer engage you, at least not to the same extent; then every day can be a feast day - today because you acquitted yourself well in one set of circumstances, tomorrow because of another.
