I totally disagree. I think you have to think and act different than other people to become succesful, afterall things that everyone can think about are more likely have been done already.
The problem is that 'being different' can be explained in so many ways, the trick is to be different in a positve way. I believe that becoming succesful can be achieved by creating as many opportunities as you can (be open to everyone), by being creative (think outside the box) and open minded (always be open to new ideas), by listening to other people (really listen, really understand what they are trying to say), by knowing yourself (your best and weak points) , by taking good care of yourself (food, sports), by having the ability to set aside your ego (so you don't miss an opportunity simply because you don't get the credits), by being as honest as possible (on the long run things will come out), by thinking long term (have a goal!), by being able to express yourself properly (don't be harsh, long winded or lying) by being able to set the right priorities (so unimportant things are not in the way) and by having courage (but also have some fear, it's healthy!).
Altough most of these things might sound obvious it's very hard to learn many things e.g. courage is something that you will get over years by doing things and overcome fears, being to communicate properly is also something you have to learn by doing, taking good care of yourself requires good discipline, etc. etc. I only know a few people that have almost all of the points and they are pretty succesful (in this case meaning a good job). Of course we also need a bit of luck. You really can't control much in life but you can create opportunities that give you a better chance on success.
