“There are two kinds of discontented in this world, the discontented that works and the discontented that wrings its hands. The first gets what it wants and the second loses what it has. There is no cure for the first but success and there is no cure at all for the second. The very worst of my vices and bad habits will abate of themselves if they are brought to an accounting every day.”
“We can shoot rockets into space but we can't cure anger or discontent. ”
“Restlessness is discontent — and discontent is the first necessity of progress. Show me a thoroughly satisfied man — and I will show you a failure.”
“Discontent is the first step in the progress of a man or a nation.”
“All our discontents about what we want appeared to me to spring from the want of thankfulness for what we have.”
“Discontent is the first step in progress. No one knows what is in him till he tries, and many would never try if they were not forced to.”
