I have noticed that when people are giving you advice, they aren't particularly concerned about convincing you of some truth or the necessity to change your ways/etc. Often times, they are trying to convince themselves of something they are having difficulty accepting. By you accepting what they say, it validates their views and makes it more likely that they themselves will buy into the advice as well. It's a form of external validation.
It's kind of annoying to be in such a situation because you are essentially being used by the person to validate themselves and convince themselves of something. Even though you are the one seeking advice, they are still focusing on themselves, not you. You have to wonder then, how useful is their advice since they are thinking about themselves, whether they realize it or not.
"I end up resigning myself by saying, it's experience and each day's little bit of work alone that in the long run matures and enables one to do things that are more complete or more right. So slow, long work is the only road, and all ambition to be set on doing well, false. For one must spoil as many canvasses as one succeeds with when one mounts the breach each morning."
