On the topic of big dreams

In relation to the death of Muhammad Ali a couple of weeks ago, I ran into a quote which might (or might not) be a Muhammad Ali-quote. I have seen it attributed to Ellen Johnson Sirleaf, president of Liberia, as well; she said it in a speech to the graduating class from Harvard in 2011. Deep down, however, it is of less importance who originally said that:

If your dreams do not scare you, they are not big enough.

- I am certain that it is true. Because if our dreams become so small and unambitious that they are mostly there for cosiness, then we have dragged them so far into the comfort zone that we should have been living them long ago, while starting to dream more ambitiously. Otherwise we have just arrived in a situation, where we do not dream. We have simply fallen asleep. (Translated from Noget om store drømme)
