I think any one can succeed in life if they want to .You just have to want it to work for what you want in any way possible plus you shouldn't let any one bring you down if you know you can do it then no matter what they say you'll just do it.
Although a university education can be an advantage, it is not always necessary for success. There are many examples of people who have been successful even though they never went to college. Also, many people who have gone to univesity are not particularly smart of successful in their later life.
In my opinion a person can succeed in life without a university education. Because education is available outside the structured university system and education is not the only yardstick to measure success. Many blue collar occupations offer opportunities for success and no degree is required. The mindset that only collage educated individuals succeed in life is a falsehood.
