Cards

I was asked to choose three cards to represent the past, now and future among hundreds of card the other day. 

I choose a seaside view with footsteps, an open book with blank pages and a wide view of sky and mountain, with a rainbow on the right side. 

The past has overed, the present is what I need to play now and the future is not far from now. It's coming after this. Very fast, very soon. 

What do the cards mean? Don't tell me you know it because even myself can't answer it. 

How can I play the cards in hand now and ruled the game?
