That's why we should always listen to people who criticizes us, especially if they know us well (and if I may add, when they stop firing at us it'll mean they don't care anymore, and that would be very bad). To quote Senator Amidala:
Our mentors have a way of seeing more of our faults than we would like... it is the only way we can grow.
I am reading several resumes, and I often find sentences like "five years experience in (you name it)". What I would like to know in advance is if that means "I've constantly grown in the last five years" or "I've repeated the same six months experience ten times". I'll let you reckon which is the most frequent case.
