Describe A well paid job

Well, its been my ambition, goal or whatever the best word I can use to it that I want to become an investment Banker in one of the well reputed worldwide banks; like HSBC, Citi Bank, American Express etc. I have the great passion for managing finance and want to work in the category of that field of highest level, where I can sense more challenging tasks, responsibilities, especially for some sinking financial business companies, I want to strive hard to make them float and thrive in a calm sea. However, there has been lot of requirements I have to bring in myself. Nevertheless, I have worked with great businessmen and managed their portfolio superbly by investing their money in international market in real estate, mutual funds, in gold, as well as by guiding them to invest in developing countries through their scheme of Foreign Direct Investment. So by being free lancer and investment consultant at a corporate level, I have been working; however, I want to see myself to work on a highest cadre of this business. I have got the idea of becoming an investment banker through my client who has been respecting me as if I had been working in an international bank. So then onward, I started dreaming and backing myself to bring that in reality.
