Why we try harder only second time?

I have seen people succeeding in their first attempt. They must be smart people but strangely the percentage of such people is very low say 1-2% but the people succeeding in second attempt is relatively huge, say well above 70%.Reasons are unknown or need to be searched? Probably they realise problems only after failure or they were not well prepared in very first attempt. There are no short cuts to success but still people look for easier ways.What could be the reasons, people don’t change easily and will not change easily they need to be consistent in their efforts towards any decided goal of them and should toil hard to get the desired results. why people get distracted after deciding a course of action is a matter of research but yes they do so. There are many motivational speakers urging people to change the way they think or act, people don’t change. There has to be some logic.
