I too am definitely "guilty" of giving out more advice than I probably should. However, some advice is good-natured (even if critical), whereas other advice is sometimes too much a projection of personal beliefs or unhelpful (i.e "That idea will probably fail"). I have definitely "grown up" a bit in terms of taking advice though - I used to think I was right about everything (even if outwardly humble). It is definitely not easy to put yourself in the mindset of another person.
