You DON’T accept that loss !
Losses hurt, winners make you feel good !
Over many iterations with small stakes you hope to gain an advantage.
if you flip a coin a thousand times a day with a mate - each of you starting with a thousand dollars, if it lands heads you win a dollar. If it lands tails he wins a dollar.
Flip that coin every day a thousand times a day for a thousand years - “Law of averages” says you both end up with a thousand dollars - BUT that is not the truth - at some point during that thousand years one of you will “Bust” the other one.
IF he starts with a million dollars and you start with a thousand - HE WILL bust you ! - just the way it is !
Now if you say to him “I’m bored with this lets play cards” - If you cut the cards 15 times and I shuffle in between cuts, IF you cut the exact same card twice in 15 cuts, you pay me a dollar - if you don’t cut the exact card twice, I’ll pay you a dollar, YOU WILL bust him over unlimited iterations, provided you have a decent stake to start with.
That then is your “Edge” and you will soon stop caring wheher you win or lose any single bet !
TRY it !
What you need is a system which is in your favour, probabilty wise. Then you will stop caring - That’s all !
