$6K is doable, just not every day. After taking losing days into account you will average or net just a fraction of that.
If you want to average $6K a day ($1.5million per year), you probably want to be making $60K (or more) on a good day.
I am talking about having an actual edge (with context as well). There's no reasons you should be having more than 10-12 losing days a year max, if even that. You may make less than that because you have to sit some days out due to context, or some days you can't make 6k, that's true. But you will also have days you make more than that.
When I say 6k, I don't mean on average. 6k is just a very minimal amount and reachable goal without putting tons of risk on the account.
