Not so long ago investing in the stock market was the privilege of a few, but mentalities changed over the last two decades and these days anyone with a bit of spare money won't be shy to put it at work. It may have started with real estate investing; At a time when properties were cheap, it was tempting to buy one and sell it back a couple of months later, making a few thousands in the process. It may now have blown out of proportion, but that's another matter entirely. The fact is that safely investing in mutual funds whatever savings we might have made early retirement easier for everyone.
That's the whole point, investing for retirement, so most of us will still favor long term investing rather than the spectacular coup that can make us rich... or leave us broke. In time many have developed a true knowledge of the market though, and a passion for the game. Those made investing books their favorite reading material and called on an investing software to manage their portfolio. They're familiar with online investing and check the state of the market several times a day.
I admire their success and positive impact on the economy... I just hope they keep in mind that the one thing truly worth investing in is the future of this world we live on.
