In my opinion competition at work, at school and in daily life can both be a good thing and a bad thing, why? because I think too much of anything can be destructive. Yes, it's a very good thing to be competitive but don't overdo it. Having no competition in your life at all can be very depressing. because you have no motivation, no goals you want to achieve, everytime you wake up in the morning. I don't believe that there is such thing as "co-operateing" too much, when you work with someone you should work together as a team and co-operate, but also do things for yourself, like something career-wise. You should think of your future in your work. That goes the same if you are still in school, take my school life for example. If I am very good at one subject in particular, lots of other students may come up to me and ask for pointers. I would be very glad to help them. If there is any homework, schoolmates may come over together, this is also fine and very good for building relations...
