It seems to me that if you or I must choose between two courses of thought or action, we should remember our dying and try so to live that our death brings no pleasure to the world.
If you can dream it, you can do it.
We cannot be sure of having something to live for unless we are willing to die for it.
Be still. Apart from this the mind has no task to do or thought to think.
The stock market is the only market where things go on sale and everyone runs out of the store.
