Possibility vs Certainty

This is one of my favorite quote from a book I read called 'Brick Lane' by Monica Ali

'Anything is possible, so everything I wanted was possible,but what about all the other possibilities? The ones we never see when we are young, but are there all along. One day you wake up and say to yourself, I didn't choose this. And then you spend a long time thinking, but did I?'.... 'The thing about getting older, is that you don't need everything to be possible anymore, you just need some things to be certain.'

I really love this quote!
