"You cannot teach old dogs new tricks"

This quote by Joseph Chamberlain recommends that it is tough, if not difficult, to teach somebody who is embeded in their methods something brand-new. The expression "old canines" refers to people who are embeded in their practices and beliefs, while "brand-new tricks" signifies originalities or abilities. Chamberlain is suggesting that as individuals age, they become less open up to alter and less happy to discover brand-new things. This could be due to a worry of the unidentified or a sense of convenience in their established methods. Eventually, this quote functions as a tip to always stay unbiased and adaptable, regardless of age.
