People who are addicted to gambling don't feel the same kick in the stomach as beginners any longer because they get used to it...
As others said, never gamble your rent and food money.
Save until you have more than 200 the minimum betting amount and then proceed to bet with a good money management system, as if you were an investor, not a gambler. Without a healthy bankroll you will lose. Without money management you will lose. Without good bet selection money you will lose.
With a professional attitude you will find that sometimes you'll be up and sometimes down. The aim is to stay in the game long term.
Never play when depressed because even though the odds are the same if you are depressed you will miss opportunities, focus on the negative and make erratic choices.
