There is a popular saying which is at the heart of many hot debates in the world of leadership and this has to do with whether the leaders are born or can they be groomed to take up leadership roles. I think this is connected to the school of thought that believes that with a longer tenure of skills honing, every young worker can turn out to be an excellent professional. Now in order to test this theory, there are many job roles being created which are specifically addressing the creation of jobs for 15 year olds.
Even if look at classical conditioning, we find a good support to the idea that this theory is viable and definitely worth a shot. More often than not, the young workers who instead of only going to school take up a job to support themselves financially, tend to be more confident and better skilled when it comes to taking full fledged professional roles in future. The ones who crumble under the pressure should not despair either, the history is full of many great personalities who were late bloomers and maybe it is just not the right time for you.
