I want to become a consultant who identifies and proposes great JV deals as well as deals in the field of M&A. What do you need to become a great consultant, bringing value to your customers and at the same time earning great money through the deals that are finalized between your customers.
You need to be analytically strong and understand financial concepts. The basic building block is understanding time value of money, discount rates, cash flows etc. Essentially, that will be your main job, to understand a firm's value. You'll have to say more on what you know so far (educational background etc) for me to dig deeper in this field.
Build your personal brand and portfolio. Start doing the work on a small level first and scale into the vision would be my answer. Option 2 find someone doing exactly what you want, offer value and land a mentor. Get connections and go the networking route.
