Education n sucess- is dere any correlation?

Well the richest people don't have PHD's, just good ideas. So they are smart, and just because they don't have high degrees dosen't mean they don't have the knowlege. Bill Gates was smart enough to know that getting a higher degree or a degree would have cost him every thing he has today because the time to capitalize on the market was when he did, not another 3 years or so down the road.
To be sucessful you simply need to know enough about the industry you intend to enter, I suppose the more information or knowlege you have about it the more succesful you will be. If you want to start a software company it would require lots of technical knowlege. If you want to start a luxury resturant you need to know about luxury cuisine. You don't have to have a PHD for making a resturant menu but you may need some secrect family recipies. You could be very successful at either, but it just depends on how the market looks, and what you have the skills and desires for.
Theoretically, Success means 'Profitable Growth' which is higher than the average market growth rate. That means a successful person should be earning more money than most of the people are earning in his field. And/Or his Goodwill should be higher than the people in his field (his name itself should be a 'Brand') ... preferably in a good way.If you think that the people who are at good position, in a good company and earning good salary are successful then I think you are aiming really low. This is what is difference between people like us and people like Ambani and bill gates. Their aims are very higher than we can think of.. and this is the main formula for their success. For them even sky is not the limit.And, regarding your last question, even I have the same question "what businesses are we taking into consideration ?"If we are talking about all the businesses then everyone will agree that success and education are not related.If it is in field of sports - Sachin Tendulkar, Kapil dev, Steffi graph, Federer... i can take thousands of name... who cares about their education.. it is just their dedication and passion for what they do have made them successful.If it is field of entertainment - again i can take thousands of names .. and their education doesnt matter.. but still they are SUCCESSFUL.if it field of science (pure science) - take any scientist - einstien, edison, ramanujan.... they got their Phds only after their inventions became famous.. and it was not other way round. I dont think they were extraordinary or had some super-natural power that we dont have. Their main quality was perseverance - inspite of thousands of unsuccessful experiments, they still believed in what they were doing... even if world did not believe in them. Again i think this is the most essential ingredient for SUCCESS. NEVER QUIT.. if you truely believe in yourself.If it is field of Business - Jamsetji Tata, Dhirubhai Ambani, Bill Gates, Steve Jobs.. I can list many more .. they all were pioneer entrepreneurs.. They had vision.. they only want to be the BEST and nothing less than that. They never cared if they are less educated... but still they always have hunger for knowledge.i would like to share a video in which Steve job is giving commencement speech at stanford univ graduation ceremony 2005.He gave mantra for success as 'Stay Hungry, Stay Foolish'.You got to see it to understand this... very good.. very enlightening speech - YouTube - Steve Jobs Stanford Commencement Speech 2005 (http://www.youtube.com/watch?v=D1R-jKKp3NA)After this you can decide, if education and success are related.
