How learning and development can help me to improve my work and further in my career?

Maybe to start you could talk about how some people in countries (typically African) can’t afford education and therefore jobs are very limited, mostly farming. They only produce primary resources (raw materials that don’t sell for much money) because their education is unaffordable or poor.

Then you are away! Because after that, you can say something about how we are lucky because we are a developed country with good standards of education.

Tip if you get stuck on development: HDI (Human Development Index) which is an indication for every country in the world of how developed it is.
