but have little to invest
Seriously, without trying to burst your bubble, considering a career change to become a professional investor with little funds will not work. If you really wanted to become an active trader where it would be your sole income you would need a lot more than "a little" to get started. I also don't recommend anyone doing this for a living who is new to investing. I have been doing this as a job since 1996 and I can't even begin to tell you how many people I know who I saw come and go. If you are retired or have a spouse who makes enough income and supplies you with health benefits it is possible, but it takes years of learning. Don't be giving up your day job to do this.
