Take time daily to reflect on how much you have. It may not be all that you want but remember someone somewhere is dreaming to have what you have.
The most valuable lessons in life do not come when you are walking or running. They come when you fall down. You better take them and rise up!
Allowances can always be made for your friends to disagree with you. Disagreement, vehement disagreement, is healthy. Debate is impossible without it. Evil does not question itself, only hope questions itself. Even the incorruptible are corruptible if they cannot accept the possibility of being mistaken. Infallibility is a sin in any man. All laws can be broken and are. Often. Like when a bumblebee flies or an ancient regime is toppled.
