Why study Management?

You might say, Why study?, perhaps the Nike slogan is right, we should all 'Just Do It!' ?

I have mellowed considerably since my youth on this subject, when I viewed all Management books and theories with disdain, and I now think there are many good reasons why, for most of us, study is worthwhile, even of subjects such as 'Management':

1)"There is nothing so practical as a good theory"
2) You are always using a theory anyway, you may just not know which one
3) Reflection on experience ( sometimes called 'Trial and error') is an excellent way to learn
4) Reading what others have figured out before you is a good way of avoiding hubris

I'll be back with more reasons as I am reminded of them...
