I am into investments of millions of dollars, there is nothing wrong in your addiction because even working can be sort of an addiction, or even this forum. But perhaps addiction is too strong of a word, it is true that investing is sort of like gambling but without investors than economic growth is much more difficult and really investors are largely "savers" (for tomorrow) who believe simply putting savings in a bank savinys account is even more "stupid" and dangerous considering the loss of value in such savings due to a weak currency or inflation or cost of living as it rises.
However we are now suddenly seeing a stronger dollar and the economy improving in US and elsewhere thanks to expanded domestic (North American) energy production, fracking, shale, electric and just plain increase in upstream energy pruduction which brings lower price at the pump thus stimulating the economy and better electric cars, etc.
To be a true investor, you have to be a news junkie following all events of the world, political and weather and wars and peace and everything, you need to know everything for the moment and adjust your investments accordingly. You need to then aim at what becomes of value, while keeping also some investments in certain under valued investments in case things "go wrong" but those would rise to offset losses. For example gold is down, heading down, but I purposely keep some investments in gold mining stocks and ventures (not gold directly) in case suddenly a major war breaks out or crazy inflation etc or the Suez Canal is shutdown and so on. You get the idea.
I hold ETFs, some bonds, a lot of large cap and mid cap stocks, oil companies (made a lot of money after these stocks initally dropped recently buying "cheap" but now coming back, and eventually even with permanent low price per barrel the cheap domestic oil out of North America sells more product).
This brings up another rule to remember. There are TWO ways a business is successful - selling a few of the demanded product at an expensive price or selling a lot of the demanded product at a cheap price. Either or brings profits to pay for more production, more employees, more research and development, more procurement of infrastructure such as in hardware.
Another thing to watch for as an investor is innovation and discovery. For example, which medical companies will find a cure for ebola or produce the product? Who will produce the four engine electric car that is soon coming (one small electric engine behind each of the four individual wheels - sounds crazy but it works and the energy-performance ratio to the energy demand-pull is over the roof).
So to be an investor you need to be part of the entire world 24x7 and also have patience. And invest in your values - because it will keep you more interested in watching the trends around that industry or sector.
