Advice from your friends is like the weather, some of it is good, some of it is bad.

The comparison to weather emphasizes variability and the need for judgment. Friends’ advice, like forecasts or daily conditions, can be helpful at times and unhelpful at others; it may shift quickly and cannot be treated as universally reliable. The line also implies that advice is not inherently authoritative simply because it comes from friendship—good intentions do not guarantee good guidance. The practical takeaway is to “check the conditions”: weigh counsel against evidence, context, and your own values, taking what is useful and letting the rest pass without resentment. It encourages independence while still allowing room for friendship and support.
