There's that age old question.
Help! My child wants to be an astronaut!
They often tell us that the only limitations we have are ourselves but, when you're young, naive, vulnerable and rudely ignored by the law, sometimes our only limitations...are our parents.
But the impossible really is possible.
When a child goes up to a parent and says 'Mommy/Daddy, I wanna be an astronaut!' the moment you convince that poor kid that it's not possible, think of something else, BAM! his life is ruined.
You get those very odd kids who want to be accountants or have some other kind of stable, boring, 9 to 5 jobs. Those kids are very rare - they only emerge when they are disillusioned teenagers, disenchanted by bad grades and overly-practical parents.
Okay, so maybe your kid will never be an astronaut, or a movie star. Maybe they don't have the brains or the skill or the looks - or so you think. It is healthy to say that anything is possible, but nothing falls into your lap and that if you aim for the moon, sometimes you've just got to settle amongst the stars.
So yes, it is possible for your kid to become an astronaut.
It is possible for your kid to become a movie star.
It is possible for your kid to become a dinosaur...okay, maybe not.
