I would say if you have a small to moderate account, you need to make sure that the horse is in front of the cart. Don't let the "trading for a living" bug guide you into a situation that is almost a guaranteed-fail situation.
By that I mean, I think the best bet is to focus on producing returns, reinvesting profits, and bulking up your overall wealth, NOT trading for a living.
Trading for a living, at least in my opinion, is really a pretty LOUSY way to make a "living".
Now if you want to trade to get rich (However you define that), that is much more realistic goal, in my opinion. Once you have a net worth that makes your living expenses seem like almost nothing, you realize you don't even need to think about, "making a living" anymore.
If you do it right, you never really need to, "trade for a living" in my opinion. That is such a limiting, "worker bee" attitude which makes the whole game harder than it needs to be.
You CAN trade and substantially grow your account while you are working and earning a steady income at a job. The best thing about doing this that for most people, the regular income makes it easier to maintain the "risk taker" attitude that is needed to add a zero or two to your account balance.
Trade to get yourself to a good place financially: Having enough so that if you wanted, you could just chill and not worry about trading or anything else. No debt, no mortgage, No pressure to trade unless the opportunity is really good... Then you can try to hit those slam dunks (while still limiting risk) and just grow your wealth. This to me is a better approach.
