Destiny and Design

I am still at lose to realise that why do we come so close to success and then not achieve it. Why are we sent on that path on the first go? Maybe to learn new lessons or to learn how to do better next time? No idea, but it is tough to accept failure. And what ever may all the great seers say accepting failure takes time .You tend to ponder over and over as to what you could have done better. How you pray for another chance to do it best. But as they say opportunity lost is lost for ever.
So now what? We sit and wallow or we roll up our sleeves and get ready to meet next opportunity.
In fact this is the time when you realise that there is a strong power beyond us controlling our destiny. We do not even realise when we turn our opportunity to failure, however hard we try.
