First of all, I will thank G-d for the windfall, then, ask HIM to grant me wisdom in the management of such amount of money.
Since I am in a very high state of excitement, under different pressures to buy this and buy that, I will take 3 days before I go to the Lottery Office to collect my cheque. During these 3 days, I will let my mind free to list anything I would always envy to buy (mercedes, sports car, luxirious house, boat cruises, trip around the world, gold necklace and diamonds for my wife, best restaurants, expensive wines, throwing a lavish party)..Then, when my mind is tired of looking for more things to buy, I will take a rest, and chase away any idea of shopping. I will take a white paper, draw 3 columns : On the left side I list those items I deem stupid, in the middle the un-necessary, and in the right the needed. I think, at this point of time, that the bulk of my initial list would be classified as stupid, then few will be un-necessary, and the only thing worthy is the gold necklace for my wife.
Of the $25,000,000.00 I have won, 10% will be set apart to be used as G-d commanded me for any tenth of my income.
Then, I divide the rest equally between me and my wife. I have a rule of 33-33-33-1. It means 33% stay in hard cash, 33% in safe investment such as treasury bonds and gold, 33% in business venture (1/3 real estate, 1/3 stock market, 1/3 reserve funds for these ventures), 1 % to pay for all my debts and to cover my usual expenses.
My goal is that 5 years from now, I will double my asset up to $50,000,000.00. Not all in cash, but in different form.
I'd like to emphasize that I am not quitting my current job, which is doing delivery (I am an independent, and drive my own truck); and I continue to use the money I earn from my work for my regular spendings, instead of taking from the lottery gain.
What could be a problem for me is if my neighbours know about it, and start to behave in a hostile manner. That way, I would move to a more discret, but decent place.
As for the big projects such as saving the world, I have no quick things to offer such as cash donation to charities or foundations. I rather will work for free for people who need a service of transportation during their moving. And, down-to-earth, if I run into homeless and hungry people, I will not give them money but good foods, like let's say a Trio Big Mac, or buy them a bit of grocery (cereals, milk, banana, sliced breads, tomatoe sauce, italian pasta, cheddar cheese, salads).
The long term goal for me is to build creating-job-infrastructures(schools, hospitals, factories) things that will profit many people and generation.
