I’m pretty new to this too but my dad always told me there were 5 things to remember,
know your game
have a good sense of willpower,
bank your winnings (even just half)
don’t drink and gamble
know when to stop.
Seems common sense really but I think it’s changed a lot since his day, I know a lot of people now who bet online, with this kind of thing bets.co.uk and there are more FOBT’s too which makes me think that more and more people are after the instant hit rather than looking at the long game.
