RE: your focus
" ... While money is my motive, it is not a factor in making playing
decisions."
Focusing on Playing Decisions is very narrow indeed as those decisions involve one hand. Not the thousand that you will be playing.
A wider focus has to do with the error you are making re: your statement about quitting when losing. Money management" myths abound. An important "wide" focus involves learning what you can about "Risk of Ruin", and how that relates to Bankroll requirements.
It surprises amateurs who want to move up to professional playing that anywhere from 800 to 1,400 units are god ball park requirements, depending on the gaming conditions available.
If you are playing a common (piss poor) Atlantic City 8 deck shoe game where the dealer cuts of 2 decks and Hits Soft 17 you would need 1,400 times $15 as your initial bankroll. $21,000 is a fair piece of change, and a solid fraction of that needs to be (literally) in your pocket when ever you play.
A 6 deck $25 game where the dealer Stands on Soft 17 but still cuts off 2 decks (e.g. Trump Plaza) is a better game - but would you'd be advised to secure 1,000 units to play with - and that is $25,000.
Your chances of surviving, as an aspiring serious player, with just a few thousand dollars is poor. Your chances of doubling your bankroll before going BROKE would be above 40%.
Can you handle a 2 out of 5 chance of busting out ?
