My worst day was when I used my school fees to gamble because I thought I will make more money to take care of some of my needs in school. At the beginning I was making profit for 2hrs,I was carried away with the anxiety of winning but later the game turned round and I was losing and losing,I didn't quit hoping I will recover my lost. Before I knew it I was left with 10% of the money I started with, I couldn't just quit the game then because I still feel I will start winning again but luck failed me and I got drained of all I have on me.
The truth of the matter is that every gambler once had a worst day in his or her life, but there is a popular saying that "What doesn't break you, makes you" and that "experience is always the best teacher", and I'm happy you have had your first-hand experience in gambling, of which I will be pointing out some mistakes which you did, and helpful tips
1. Never gamble with an amount you can't afford to lose
2. Never you think you can win a jackpot by playing continuously.
3. Always know when to quit while gambling, because it's not a do or die affair
