This quote by William Shakespeare is a suggestion that too much of a great thing can be a bad thing. It is a warning to be conscious of our actions and to not take advantage of the advantages in life. Excessive of anything can result in negative consequences. For instance, if someone is given too much cash, they might become greedy and self-centered. If someone is given excessive power, they might become corrupt and abuse it. Excessive of anything can lead to an imbalance in life, and this can cause negative results. The quote is a reminder to be conscious of our actions and to not take advantage of the good ideas in life. It is a suggestion to be content with what we have and to not overindulge in the good ideas.
