One must try and achieve whatever goal one has. If you want to be the owner of your own island, you have to try and generate wealth so you can own one. Like one of those Bond film villains who all seem to live on an island-could be just a correlation, and not causation! Also, Bond could come and destroy it all, so think carefully.
But the point is, if you want quick money, you can try and trade in something that has the potential to get you there (with the downside being that it may wipe out what you have got)- real estate, stocks, commodities, or any other legal methods of gambling (include Las Vegas trips, and lotteries).
If you want long life, you should not go out on the road, because given our traffic, anyone can kill you in a minute -it's dangerous out there. I can vouch for it-I nearly got killed a few months ago. But seriously, you may have to get into watching what you eat, and exercise (why do I see a frown on your face?) and so on.
If you want to be happy, all you need to do is smile a lot, read funny stuff (Wodehouse, Woody Allen, Bill Bryson, Dave Barry etc..) and generate smiles around you. Sounds easy? Then try it-but only if that's your life goal.
