In a sense, I absolutely agree with you - because you said the 'individual' is as strong as his will to succeed, you didn't say that as long as the individual has a strong will he will succeed. My father once told me that diamonds formed under pressure, and that if you can look back or stumble upon true stories of people that accomplished great things, and led helpful and friendly lives with everyone they met. Some people like this were made into who they are by dealing with some of the worst of circumstances - possibilities are endless. I can say this confidently as I've seen it before, but I can't find myself honestly agreeing that these types of people always succeed. Sometimes things go wrong and the good face darkness while they're conflicting people led rich, easy lives. It's a sad thought, but I suppose that's the way of the world. All you can do, is try.
