In a previous life (ie. before I got married and had the children), I was an accountant, and worked in the Corporate Finance department of a UK Plc. The company was going through an aggressive expansion, and I got to see first hand how mergers, and takeovers are done in the corporate world.
The job was not really me, and I was quite glad when I left it and walked away from the corporate world. But now I come to think of it, it is amazing what I learned, which I am now using to great effect in the way I do business.
