This song is about someone growing old, looking at someone who is a lot younger than them. They remember when they were their age and experienced the same things they did and is comparing both of their lives. They are saying that they've stopped questioning things and have learnt to accept things and that they are singing and voicing opinion because it is all they have taught themselves. They are then asking what is important to them and what they are good at and they should follow it.
