If your BS detector goes off, that’s a good thing. Because if you are struggling just like someone else, then you should be commiserating with them, not criticizing. And commiserating is more fun to do; it’s a bonding experience and takes some sting out of our failures. Sometimes its even just the thing to muster the courage to make changes you‘ve been thinking you need to make!
Which is great! Because perhaps once you’ve actually mastered the path you are telling someone else they should be taking, your words could be useful. But until then, resist the urge to criticize people and just walk along side them.
