This reminds me of that meme that say somelike, if I win big, no one will know but there would be signs.
1. Let the money sit in your bank account (wallet) for at least one month. It will allow you to settle down your heightened emotions. Just let the amount sit and do not do anything with it for at least one month.
I thought this would be take a brief break from gambling. If you let the money sit in your bank account for at least one month but continue to gamble, there is a probability that you will use it for gambling.
2. Go on a low-cost, week-long vacation with your family and friends (do not tell anybody about your winnings; do not boast) immediately. It will help you make your relationships stronger and will certainly help in doing step 1.
Agreed but first solve any pressing need first or invest where there is none before any pleasures.
3. Do not change your lifestyle immediately, as it will help you to remain disciplined, which will eventually help you out to earn even more.
No bling, blings you mean. Also the same with your previous point.
4. Invest in a diversified portfolio other than gambling, probably for the long term, at least 80% of your winnings.
Well, if you don't understand any of the investment stuff, better to save your money rather than lose it in a investment you don't understand.
5. If your winnings are even greater and allow you to quit your job, then use your time to learn finance.
It is not a sustainable income source so don't quit your job unless you have a solid plan in place. And that solid plan should be how you'll live off your big win.
