But many people look at at in a different angle. They think that the other person is unnecessarily abusing us for no fault of us. It may be true also in some cases. So before coming to that decision one has to introspect himself and understand the reality and act accordingly. If we follow this process we will be successful in our life.
But this will not be in all cases, some people with less self confidence will take abuses very seriously and they will go into the dilemma that whether they can do or they can't do. And they start thinking that they can't do that work and will leave that work.
So the person who have a self confidence can take the abuses, critics in a positive way and will work hard to get the work done, to prove themselves. So all of us have to develop self confidence so that no critics can do us any thing.
I think the will to do something comes from within us. We want to do it so badly that we keep trying till we succeed. The actor in your example wanted to succeed. He was not getting the recognition that he desired, so he basically worked to get that. I do not think that people's comments would have been his motivation. He wanted to succeed for himself, not to prove people wrong. We, after all, live for ourselves, not for others.
As long as we have the spark in us, we can outshine anyone and anything. It must come from within.
Underestimate me...that'll be fun!
These phases of life create new sparks of determination in our life only to prove that what we were and how much wrong the perception of these misbehaving people was about us.
Knowledge is power.
