What career should I pick?

Start your own business farming octopus in third world countries. Dredge their estuaries to create the farms, then when we, the shareholders, are all rich on your success you can dredge the estuaries further to create marina's for us to moor our sparkling new yachts in which we bought from all those lovely dividends to are going to pay us. You will not only be rich, you will be admired.
