The money is just a natural byproduct of seeing the markets correctly and trading well.
I have never seen someone say to themselves: "I need to make $10K today, bills to pay" and then squeeze $10K out of the market that day.
In fact, speaking for myself, whenever I force a trade nothing good really comes of it.
It would be a very reasonable expectation, however, to correctly interpret the market price action, follow your trading plan quite well, and be positive P&L for the day. Do it consistently, and it becomes a living.
