Education is not the only key to success anymore, then we all be believe that, if we don't go to school, we can't make it, the country is something else, we should find all means to be a successful person in life, education is good, but we have to find all means to make it, country which a graduate is riding bike, someone that spend thousands of naira to go to the school, is now riding bike, imagine,
So is always good to invest in once self, than working under someone, which you won't have time for yourself,
Just an advise
Yes, education is not only key to success but one of the essential parts of success.
You can't ignore the value of education to any extent.
Also, I agree that you should invest in once self, but you can't assess the right way to invest in yourself unless you aren't adequately educated on what to do and how to do it.
Education is certainly the most important thing to make life better, without education, it is impossible for a country to reduce or eliminate poverty, and this is the target of many countries to increase the education budget.
