I don’t know the key to success, but the key failure is trying to please everyone. (From a comedy story-teller)
It’s unlikely that anyone is looking for the key to failure, but the warning here is worth noting. To climb the ladder of success, it might seem a good idea to please everyone; perhaps, they’ll help you in your ascent. But the road to achievement is often strewn with people-pleasers who discovered they could not please everybody.
