Considering playing Blackjack to supplement my income. Tell me if you think my approach is realistic.?

My first time playing Blackjack in Vegas with 0 knowledge i left up $200 (max up $300). Of course it was small stakes $5-$25 bets.

Now i know Basic Strategy, and I’m a decent counter. I live by these rules at the table (based on the same $5-$25 stakes) .

1. Never play with less than 20 minimum bets.
2. If i go down 10 hands in a session leave.
3. If i go up 20 hands in a session leave.
4. If i lose $100 after making $200 leave.
5. Maximum session time 2hrs unless a previous criteria is met.

I know a lot of people will say that I’m leaving a lot of money on the table with these rules, but I’m not looking to get rich. If i can double my money in a session I’m happy. My goal is to make $300-$1000 based on these rules.
Maybe I shouldnt have said “supplement my income”. This is just to bring in more play money, the money I’m playing with is after i have taken care of all obligations that i have, and after putting away some for savings.

Thanks Leg, and Sandy for the insight.

PDQ thank you as well, but im not new to the gambling world. I know all about luck and I’ll be the first to admit my first session was lucky.

My goal here isnt to make more money that i “need” but to make more money to gamble with.
