I think the virtue I prize above all others is curiosity. If you look really hard at almost anybody, and try to see why they're doing what they're doing, taking a dig at them ceases to be what you want to do even if you hate them.
I came in haste with cursing breath, And heart of hardest steel; But when I saw thee cold in death, I felt as man should feel. For when I look upon that face, That cold, unheeding, frigid brown, Where neither rage nor fear has place, By Heaven! I cannot hate thee now!
When young lips have drunk deep of the bitter waters of hate, suspicion and despair, all the love in the world will not wholly take away that knowledge. Though it may turn darkened eyes for a while to the light, and teach faith where no faith was.
I know there is a God, and that He hates injustice and slavery. I see the storm coming, and I know that his hand is in it. If He has a place and work for me - and I think He has - I believe I am ready.
Do not waste the vast majority of your life doing something you hate so that you can spend the small remainder sliver of your life in modest comfort. You may never reach that end anyway. Resist the temptation to get a job. Instead, play. Find something you enjoy doing. Do it. Over and over again. You will become good at it for two reasons: you like it, and you do it often. Soon, that will have value in itself.
