Most of the time we spend all our energies on worrying about failure. If we could only just brush it out and retain our energies – we could move forward and look at fresher avenues. A mind which is insecure and confused, cannot think clearly. And when one is in a state of what is called – depression, it is to avoid this kind of thing that the Gita talks about Karma Sanyasa Yoga. Means perform your Karma, and forget about the result.
