You work 10 hours a day (at the minimum). You negotiate with Suppliers making sure the company gets good deal while the poor supplier gets almost nothing. You deal with a lot of super egos from different groups. You deal with people who’s heads are only for hat racks. You don’t rest when you get home but fight with your sssslloooowwww laptop so you can make the latest changes on a presentation. After all this, your project gets approved by the CEO. And who gets the credit?
