"Life is easier when you enjoy what you do"
We should be always careful only. The mistake we commit will have an effect on us also. So we should try not to do mistakes. Do your best and try to be always honest and sincere. Then once in a while, a mistake happens also people may not lose trust in you. But if we are doing, again and again, mistakes, nobody will have trust in us. This is the fact.
What the author has written about is not a matter of mistake, rather it is a matter of any activity or action carried out deliberately by someone due to a kind of greed for some gains. It spoils the image of a person and creates a question mark on his credibility also. Once the credibility of a person is lost, I think everything is lost.
