At one time or the other everyone feels stressed. And on those times we choose to worry about what all can go wrong, what all is against our success, how by a single mistake everything can get ruined, blah blah blah.
And in those few moments we tend to loose all our hope and confidence in ourselves. Further efforts go waste as we do them thinking we are not worth.
What we forget is hope is that light which pierces darkness. Even if it be bleak, hope lends warmth to the soul and the courage to walk further.
Walking in a wrong direction is still better than staying still at a place with no progress at all.
