Oyster anyone?

Constantly I am being reminded of my "youthfullness". With being a youth, it means I have a lot to offer, I know nothing, and I can't be set in my ways because there hasn't been enough time for my "ways" to set. Which means that I am the perfect type of person for older people to put upon their  advice.  I'm sure I have heard the same advice more than once, but it is very much appreciated.

"The world is your oyster. You are young and pretty and smart, don't let it go to waste aye"

So many people have said  that to me. 
 Right now though we find ourselves at that in-between stage where you aren't a kid and then you aren't really an adult either. I like to think in some cases I'm  "kid" , and in others I'm an adult, for example if I was to go out for the night I'd expect not to be waited on, because I am "of age" by law, and whether the people that are meant to be responsible for us like it or not, we are in fact responsible for our own actions, no matter how absurd they may be, we can only save ourselves. 
 In the case where I would be seen as a child or even when it is acceptable, is when I am in a situation where I am out-numbered by people who are older than me. Which usually puts me in a position instantly where my manners are on the money, and I am on my best behaviour, and keep my foul language to a minimum or none at all.I guess this seems to happen to people no matter how old they are.
 It is very hard to let the older adults know what we are faced with when it comes to making decisions about our lifes journey.
 For some of us independance comes naturally, we are not co-dependant, and we can manage pretty well on our own. For the rest of us it is hard to understand the realities of life outside a home environment. We may find it hard to be independant but what we lack in independance we may have strengths in other areas. With the independant ones, we may find a lack of skill somewhere else.
  The thing that comes to my mind is, "I know it is a wonderful thing if you know the oyster has the pearl in it", in reply to 'the world is your oyster....'. And one day I know if I get to be old I will not be pretty anymore, do not be surprised if you hear me agreeing when someone says something nice about my appearance, because I know it doesn't last.
