Most of the times the small failures are small enough to determine your next move.
The big success is never the overnight success. The big success is usually always the result of staying resilient amidst the seemingly small failures.
Nothing is a failure if you are willing to look at the learning of gold that came out of it. Those who do, are going to save themselves years of effort and happiness.
Happiness, you see, does not happen on a Sunday monsoon morning. Happiness is simply making the decision to be happy even when outside world has decided otherwise. Which, btw, takes one small step, in a different direction.
