The average persons capabilities.

[RozKek]

Hey, before I start off I want to tell you that I'm not sure if this is the right section to post this in.

But my question is how much do you agree with this statement and why:
The average person with a good life, e.g good family, good education, good friends, living in an educated country, and is psychologically healthy can with effort learn, and become almost anything or at least lots of things (job wise), for example, learning to draw, becoming good at mathematics, good at sports, becoming a doctor, lawyer, scientist etc. (Not all at once of course)

For some reason it was difficult for me to phrase this question, but I hope you understand what I mean and if something is confusing, point it out and I'll fix it.
And I chose the atheist section because I thought people here would answer more realistically and more scientifically but anyone regardless of religion is more than welcome to post.

So the question is can an average person with pretty good resources get a pretty good job with effort.  The answer would be yes and it seems so simple I don't know why you would ask.

My intention when asking this question was to know if others thought that let's say not every "average person" can become/learn almost anything because of genetic limitations, etc. Maybe I wasn't clear enough, and I already said phrasing this question wasn't simple for me, english is my third language, so I have some difficulties.
