Why do some people succeed without apparent effort? Do we take it for granted that these people are simply luckier than the rest? Do we think it is a matter of chance or unfairness? Some people are born with certain innate abilities, or in certain family and/or economic environments that by nature make it easier for them to achieve success, but all this does not guarantee anything if the person does not exploit those abilities. On the other hand, we can find people with profiles to whom things have not been easy because they do not belong to these wealthier groups.
