The thing is that if you don't have a good understanding of how this game works you are becoming a loser, like in everything else.
It tries your limits, tests your patience and discipline, doesn't care about your emotions, neither about if you are good or bad, the only thing which being rewarded is what you can do, the same goes for the world.
There is not any progression which can endure all sessions, variance is formidable foe even for the best of progressions, happens very few times but just once is enough to wipe out entire bankrolls.
And when this moment arrives what would you do?
You must spend almost the whole day at the table with vast bankroll in order to turn such situation around.
It becomes pointless because you are risking too much in order to gain too little, the best in such occasions is to be absent, but how could you know, you realize it when already late for maneuver.
That's why you need a plan, winning every day/session is not realistic but having a net profit every 7 days/sessions is realistic with the proper plan.
Variance is a wild beast which cannot be tamed by progressions, progressions seems to work when variance is milder, usually is but that's not enough.
So such time and money is far beyond the reach of average gambler, but even if you had would it worth?
I understand risking 100,000 to make 10,000 or more, not to take 1,000 or less, or even worse by chasing your loss.
Have you any idea what you are dealing with?
Step number one, know your enemy.
Step number two, control yourself and you'll control the game.
Step number three, set a realistic plan in action by focusing in medium term.
By completing the initial smaller things we have made a big step towards success.
It's true that like in life, roulette shows that nothing is equal, while probability theory shows how things should be, it remains just a theory but what we see in everyday life is not what should have been but what actually happens.
Consider results as cards of a deck, they are repeating with different order each time, when your progression could win any possible order of the deck, then you would be a long term winner.
That's what variance does, it's changing the order of the events, that's why linear progressions will never work.
Where is the end of the rainbow?
You never know, you don't want to know, so instead of swimming against the torrent why don't you let it drift you away where the rainbow ends?
