I am sitting at my desk trying to calm myself down and hating myself for being STUPID. And normally when I say stupid I am talking about some emotionally driven decision or action - and I am that kind of stupid on an almost perpetual basis. I have basically come to terms with being 'that kind of stupid'. The kind of stupid that reduces me to tears of frustration and self loathing is the "HOW CAN YOU NOT FUCKING GET THIS?!" kind of stupid. Usually involving some kind of math/data. I hate that I can't work it out for myself - I HATE that I don't get it when someone explains it to me and it still makes no sense and I really really hate it when I make the person that is trying to so frustrated and annoyed with me for NOT getting it that they tell me I "don't need to understand it - I just need to do it". So if I have something that costs £35 and I want to make a 65% margin I need to take my £35 and divide it by 0.35. £35/0.35 = £100. Fine. But if I sell it for £70 I have made 100% profit. My MD tells me that GP (gross profit) is the SAME as margin. How can that be true. If my profit is 100% but my margin in that instance would be 50%??? I am not really expecting anyone to explain this to me - apparently I am far too fucking stupid to understand if you try. Believe me, people have tried. I just really needed to vent before I cry at my desk.
