"Can you support yourself trading for your own account?"

I fail to see the relevance of this. Do you mean trading from/in your own account or something else?

How an advisor would recommend a client invest should not be based on how they are investing. There are different risk tolerances, timelines, and uses for the monies. It is fair to assume that their advisor might be more personally aggressive than how they would recommend the OP invest.

If you mean to say they should be able to financially support themselves from the profit from their own account, again, that does not seem relevant.
