If you plan to be a professional registered investment advisor, prepare yourself to a "sales person" job where you will be selling funds for commissions at the beginning and maybe to the end. Nobody will take you seriously unless you have a prove that you have already made a fortune for yourself. Everybody will tell you "if you are investing expert than why don't you invest by yourself". On the other hand, if you made a fortune by yourself, you do not need to work for others.
If you want to be an investment expert for yourself - learn.
If you're really an expert, than trade for yourself, establish a long term verifiable performance record, than you will be in demand by the hedge funds. Worked for me. :-)
If you're looking to invest for others, don't. Become an analyst instead. Nobody hires newbie investment brokers unless they can actually invest and successfully earn money themselves. And if you could do that, then you wouldn't become a broker.
If you're planning to be an at-home investor on your own personal computer, then there's not really much to advise. The sky's the limit.
Read the life histories of Warren Buffett and Bernie Madoff. If you can see the difference, good for you.
Any advice for someone who will pursue a career as an investing expert?
