#3. Gambling requires discipline: Yes, gambling requires discipline . As a gambler, you don't need to stake every hour or every day. You could set a weekly profit target for yourself and once you hit the target, you wait for the coming week, you don't need to be greedy because gambling doesn't favour the greedy ones and you also need to do your proper findings before going to market, your findings could take you days, so as to reduce the risk
I wouldn't call them secrets but rules and the most important one is #3-Discipline because without it you definitely don't go to far. Your stake/bet should be max 5% from your bankroll, adjust your stake when your bankroll reach half or double and your motto should be >bet less win more<.
