It is really simple but you have to find a way to stay in the game. If you do your complete balls and have no bank left, there can be no more bets. There is always another tournament/match/race. Always another day. If you have to lower your stakes then so be it.
It’s amazing how often after you have had a bad run that something with huge standout value arrives. You don’t want to be left cursing yourself that you cant place the bets that you would have normally because you had chased on some rubbish.
I remember in the early days of my betting doing this. Simply no worse feeling. Stay in the game and you always have a chance. Be really patient.
