We just say, “I am successful” or “I am a failure”. The more important question is, what are you failing at? Equally, the more important question is what are you succeeding at? Or is it so that we didn’t bother to go deeply into that, and we just went by the commonly socially accepted definitions of success and failure?
Do what is worth doing. Failing is not a problem, provided you are failing at something worthwhile; and then failure would not mean so much to you. Equally, success too will not mean so much to you. It is the doing that will matter. You will say, “I am grateful I am getting to do what is worth doing.”
