Age does not define our knowledge, it doesn't mean that you are 35 years old you are any smarter than a 15 years old. Yes, experience you may have lots more than a 15 years old has, but knowledge, im afraid no man can judge how wise you really are. :)
So, how old or young you are, be humble with you knowledge, there's always people that know more than you do.
Be humble.
What's the fun in being arrogant?
If people have such a low expectation on you, you can amaze them. :) kan?
