"If you hold a cat by the tail you learn things you cannot learn any other way"

This quote by Mark Twain is an amusing way of stating that often you have to experience something hard or unpleasant in order to discover something important. It recommends that if you want to take risks and put yourself in uneasy situations, you can gain understanding and insight that you would not be able to get any other method. This might be translated as a metaphor for life, as in some cases we have to take threats and put ourselves in difficult situations in order to discover and grow. It could likewise be translated as a pointer to be open to brand-new experiences and to take risks in order to gain understanding and insight. Ultimately, this quote is a suggestion that sometimes we need to take threats and put ourselves in unpleasant circumstances in order to find out and grow.
