Quote by John Milton Cage
If someone says can't, that shows you what to do.
This quote implies that when someone expresses their inability or disbelief in achieving something, it serves as a motivation to prove them wrong. It suggests that instead of being deterred by their skepticism, it should be seen as a challenge or an opportunity to demonstrate one's capabilities and determination. The quote encourages using the doubt or negativity of others as fuel for success and taking it as a call to action.
If I would be a young man again and had to decide how to make my living, I would not try to become a scientist or scholar or teacher. I would rather choose to be a plumber or a peddler in the hope to find that modest degree of independence still available under present circumstances.
