Do we really need education to become successful?

We all know education is the most important thing in everyone's life but to say education is needed to become successful is totally fallacy and nothing more.there are two things that i would mention here.these are knowledge and education.education is used in the limited sense but the word knowledge in the broader sense.education is a distinctive part of the knowledge.If we see knowledge as an ocean then education is like a pond in the ocean.everything that we learn from the childhood is knowledge but the thing that we are taught in the school,college,university is education .actually i want to state that there is no need of education for being success.you can't measure the success by education................,...............
.we see that there are many people who even did not complete thier high school education is successful today.there are many examples that i want to cite here.we all have heard the name of sachin tendulkar,the master blaster, the god of cricket,he failed in the 10th std. exam. bill gates did not complete his university education .Rajnikant was a bus conductor at the age of 25. but they are all successful today,there are many more examples in this regard. as far as we are concern about success.success is not the thing that you can measure by scale but it's the thing that is measured by one's satisfaction.whatever thing we are doing.If we are not contended with our job. it clearly indicates that we are not successful and it also shows that we are not cognizant of the actual meaning of success.
