Trying not to think about it...

I've been ttc for 10 months with no luck. It's all I think about in any spare time I get! How on earth am I suppose to 'not think about it and then it'll happen' when it's all I want? My partner is 14 years older than myself so I feel we need to get pregnant quickly so we've got time to have more but it's just not happening :( I need a miracle!!
