Ideally, the person you're giving advice to should come to the conclusion on their own. Your advice just nudges them in the right direction. Dale Carnegie gives a great example of how to do this[1].

Otherwise, the advice can come across as criticism/attack. When attacked, the natural response is to defend. No matter how right/wrong each party is. Usually advice is some form of "you're doing this wrong; you can do this better." So always start from a place of agreement: what are they doing right/well?
