"In the end, we will remember not the words of our enemies, but the silence of our friends."

Money is overrated. Truly new things rarely need an abundance of money. If that was so， billionaires would have a monopoly on inventing new things， and they don’t. Instead almost all breakthroughs are made by those who lack money， because they are forced to rely on their passion， persistence and ingenuity to figure out new ways. Being poor is an advantage in innovation.

Hope is a good thing, maybe the best of things, and no good thing ever dies.
