In my experience of corporate life, the biggest obstacles are Fear and Hatred. These are especailly the obstacles faced if you are different in some way - racially or personality -wise, also if you are a woman.
It is a major spiritual challenge. And so far I would advise that whatever happens - don't let the fear or the hatred enter YOU. Because if you do, you are the one that is doomed.
My advice is to find tactics that will help you move forward relentlessly - don't give up, at least before you have got what you want. Could give a lot more advice, but just wanted to put forward the very grim reality of corporate life for those who may be different in some way.
